Local Internet Registries . Training Course . http://www.ripe.net 8
What is RIPE?
• Réseaux IP Européens (1989)– RIPE is a collaborative organisation open to all
parties interested in Internet administration, development and network operations
• RIPE is– open forum
– voluntary participation
– works by consensus
– NO legal power does NOT develop Internet Standards

What is the RIPE NCC?
• Network Co-ordination Centre– The RIPE NCC is a “co-ordination” and support service for
its members and RIPE community
• One of 3 Regional Internet Registries (RIR)
• Why a NCC ?
Actions agreed in RIPE community needed– continuity and professionalism– neutrality and impartiality
Local Internet Registries . Training Course . http://www.ripe.net 14
RIPE NCC History
• Birth - April 1992– TERENA legal umbrella
• Became RIR in September 1992
• Contributing LIRs in 1995
• In 1998 independent
• A new structure (ripe-161)– not-for-profit association– General Assembly of all members– Executive Committee of elected nominees
Local Internet Registries . Training Course . http://www.ripe.net 15
Formal Decision Making
“Consensus” Model
RIPE proposes activity plan
RIPE NCC proposes budget to accompany
activity plan (ripe-213)
General Assembly votes on both
activities and budget at yearly meeting
Local Internet Registries . Training Course . http://www.ripe.net 16
Vital Statistics• Statistics 1992
– 3 staff members– No Local IR’s– 182,528 hosts in European Internet– 7,955 objects in RIPE database (June ‘92)
• Statistics Now– 67 staff (22 nationalities) 2,595+ participating Local IR’s 12,088,135+ countable hosts in the RIPE NCC region 3,792,085+ objects in the database

RIPE Database (1)
• Public Network Management Database
• Information about objectsIP address space inetnum, inet6num
reverse domains domain
routing policies route, aut-num
contact details person, role, mntner
• Server whois.ripe.net• UNIX command line queries
• http://www.ripe.net/ripencc/pub-services/db/
Local Internet Registries . Training Course . http://www.ripe.net 23
RIPE Database (2)
• Software Management– RIPE NCC– Database Working Group (RIPE community)
• Data Management– LIRs – other users– RIPE NCC
• Information content not responsibility of RIPE NCC• Protection mechanisms not default, but strongly encouraged
Local Internet Registries . Training Course . http://www.ripe.net 24
Migration to DB Version 3
• Re-implementation of DB software– re-written server and client – Routing Policy Specification Language
• RPSL compliant– some attributes and objects changed
• e.g. mandatory protection of inetnum-s
• most changes in the RR
– user query scripts need re-writing
• Everybody will be affected!
• http://www.ripe.net/rpsl/
Local Internet Registries . Training Course . http://www.ripe.net 25
Database Migration Time Line
• 23-Apr-2001: switching to the RPSL database– queries return RPSL only
– RIPE-181 updates possible; automatically converted to RPSL
Date | 23 April | 14 May | 15
October----------------------------------------------------------------------RPSL |[email protected] | [email protected]
RIPE-181|[email protected] | [email protected] | N / A
• 15-Oct-2001: RIPE-181 updates no longer possible
26Local Internet Registries . Training Course . http://www.ripe.net
Querying RIPE Database
Local Internet Registries . Training Course . http://www.ripe.net 27
Basic Queries• Whois (command line, web interface)
– searches only look-up keys– returns exact match– some inverse look-ups possible using “-i” flag
• Glimpse - full text search• Look-up keys - usually the object name
– person, role: name, email, nic-hdl– inetnum: address (or range), netname
• Inverse keys– notify, mnt-by, mnt-lower, admin-/tech-/zone-c,
Example
28Local Internet Registries . Training Course . http://www.ripe.net
Creating Database Objects
Local Internet Registries . Training Course . http://www.ripe.net 29
Creating person Object
• Check if person object exists in RIPE DB– whois {person’s name; email address}
– only one object per person
• Obtain and complete a template whois -t person
– -v (verbose)
Send to <[email protected]> see “The DB Transition Handout” (23.4.01-15.10.01)
• Each person object has unique nic-hdl

First Request LIR wants a block of IP addresses
– e.g. for own network / infrastructure• do not include needs of customers yet
– no need to justify usage of the whole allocation
• Steps: Complete request form ripe-141 Send request to <[email protected]> RIPE NCC evaluate and approve request
• With the first ASSIGNMENT approved, RIPE NCC also makes an ALLOCATION– default minimum size /20 (4096 addresses)
Local Internet Registries . Training Course . http://www.ripe.net 45
First Request Approved
RIPE NCC hostmaster enters allocation and assignment objects into the RIPE database only at the first request- /24 & /25 & /26 (448) instead of /23 (512)- at the beginning of the block (can be modified later)- with RIPE-NCC-NONE-MNT (or LIR mntner)
• Whole allocated range can be announced immediately
• AW=0– Every request has to be sent for approval to RIPE NCC

• Add comments
Example: Goody 2 Shoes
Local Internet Registries . Training Course . http://www.ripe.net 68
Current Address Space UsageEvaluation
• Are there any previous assignments?– ask customer
• Querying the RIPE Database– whois.ripe.net
• exact match
– http://www.ripe.net/ripencc/pub-services/db/1 full text search using glimpse2 whois web interface
• Can request be fulfilled with previous assignment?
Local Internet Registries . Training Course . http://www.ripe.net 69
Evaluation -- Addressing Plan• Do totals in “Addressing Plan” match numbers in
“Request Overview”?
• Are all subnets classless?– are the subnet masks real?
• Utilisation and efficiency guidelines: 25% immediately, 50% in one year
• Can address space be conserved by using– different subnet sizes?– avoiding padding between subnets?
Local Internet Registries . Training Course . http://www.ripe.net 70
Private Address Space• RFC-1918 (Address Allocation for Private Internets)
• Suitable for– partial connectivity– limited access to outside services
• can use application layer gateways (fire walls, NAT)
• Motivation– saves public address space– allows for more flexibility– security
Local Internet Registries . Training Course . http://www.ripe.net 71
Possible additional information
• pointer to web site deployment plan new technologies purchase receipts topology map (design of the network)
– can be faxed– handled and kept confidentially – include ticket number and Reg-ID

(New) Technologies
• If special hardware/software is used• include the URLs of manufacturer’s sites if available
• Special allocation and verification procedures apply static dial up assignments
IP based virtual web hosting• cable modems, ADSL
• GPRS?
– recommended
investigate and implement dynamic assignment technologies
whenever possible
} STRONGLY DISCOURAGED
Local Internet Registries . Training Course . http://www.ripe.net 74
Evaluation -- Network Template• inetnum value (look-up key, unique)
– specifies the size of assignment– actual range is not necessary
• Relevant netname (look-up key, not unique)– descriptive; uppercase letters, numbers & “-”
• RIPE NCC’s only reference to LIR’s assignment
• Contact persons– can be multiple reference nic-hdls (may be a role object)– admin-c responsible for the network, able to make
decisions– tech-c technical setup of the network
Protection is mandatory – mnt-by: BLUELIGHT-MNT
New in RPSL!
Local Internet Registries . Training Course . http://www.ripe.net 75
• Wait for the approval from <[email protected]> prior to assignment and registration
• Decide on the range of addresses within your address space– classless assignment on bit boundary
• Update local records for later reference– archive original documents with assignment
Assignment for customer’s network
Assignment for LIR’s network
Internal Administration
Local Internet Registries . Training Course . http://www.ripe.net 76
• Address space is considered in use only if registered in the RIPE Database
• Register all end-users separately– avoid overlapping inetnum objects
Local Internet Registries . Training Course . http://www.ripe.net 77
Assignments to (Small) ISPs
• LIR cannot allocate address space to an ISP • If the customer of LIR is an ISP, distinguish
– ISP’s infrastructure
– ISP’s customers
• Separate assignments need to be– requested
– evaluated / approved
– registered in the RIPE Database
Avoid overlapping assignments – i.e. “big” assignment/object for ISP & all its customers,
plus for separate customers

Creating network object
• AW=0– take the “network template” from approved ripe-141
form
• AW>0– whois -t inetnum
• Send to <[email protected]> see “The DB Transition Handout” (23.4.01-15.10.01)
– with the keyword NEW in the subject line
Transition to RPSL!
Local Internet Registries . Training Course . http://www.ripe.net 80
Pay attention to...
• insert the address range in the ‘network template’ from the request form approved by the hostmasters
keep the same netname attribute– “How to choose the netname”
• in the change attribute use current date• or leave out the date completely
protection is mandatory • mnt-by: BLUELIGHT-MNT recommended: include mnt-lower

Querying Address Ranges
– whois [customer’s IP range]– whois [customer’s netname]
• not unique search key
– whois -m [your allocated IP range]• will show list of all LIR’s first level customer(s) network(s)
• first level more specific address ranges
– whois -L [customer’s IP range]• will show LIR’s own allocation object

Assignment Window Policies and Procedures
Local Internet Registries . Training Course . http://www.ripe.net 85
Assignment Window Policy
• Assignment Window– maximum amount of address space LIR can assign
without prior approval of the NCC initially AW equals zero gradually raised
• Why necessary?– support to LIRs during start up
– familiarisation with RIPE NCC procedures
– align criteria for request evaluation
– maintain contact between LIRs and RIPE NCC
Local Internet Registries . Training Course . http://www.ripe.net 86
Initially: AW=0
• SendEVERY customer’s request
and
EVERY request for assignment to your own infrastructure / network
to the RIPE NCC for evaluation
• Separate request forms needed• Do not send too many at the same time
Local Internet Registries . Training Course . http://www.ripe.net 87
When is AW Size Raised
• Understood procedures• Complete NCC documentation
• Experience– with RIPE Database– different policies– evaluating and processing requests
Not always automatically raised approach us
Local Internet Registries . Training Course . http://www.ripe.net 88
When is AW Size Lowered
• New staff need training
After negative auditing report

Reverse Delegation Procedures
Local Internet Registries . Training Course . http://www.ripe.net 94
What is Forward and Reverse DNS Delegation ?
• Forward Delegation– enables naming of IP hosts on the Internet– hierarchical authority for domain registration
• organisational structure
• Reverse Delegation– enables association of IP addresses with domain names– hierarchical authority for reverse zone
• depends on who distributed the address space
– reverse delegation takes place on octet boundaries

Local Internet Registries . Training Course . http://www.ripe.net 96
Why Do You Need Reverse DNS Delegation ?
• All host-IP mappings in the DNS (A record) should have a corresponding IP-host mapping (PTR record)
• Failure to have this will likely– block users from various services (ftp, mail)– make troubleshooting more difficult – produce more useless network traffic in general
Local Internet Registries . Training Course . http://www.ripe.net 97
Overview of the Request Procedure
• LIRs have to request reverse delegation• /24 zones are delegated
– to LIR / end-user – as the address space gets assigned
• Steps valid assignment of address space /24 reverse zone setup
on LIR or end-users nameserver(s), or both send domain object to <[email protected]>
• include Reg-ID
Local Internet Registries . Training Course . http://www.ripe.net 98
“Valid” Assignment
• According to ripe-185 policies Within “Assignment Window”
- or approved from RIPE NCC Hostmaster
• inetnum object registered in RIPE Database– netname attribute is NCC's only reference if
assignment approved • do NOT change netname without notifying
this is mentioned when we approve your IP requests
– registered after the approval date
Local Internet Registries . Training Course . http://www.ripe.net 99
/24 Reverse Zone Setup Recommendations
• At least two nameservers required– one nameserver setup as primary– at least one other as secondary
• SOA values reasonably RFC1912 compliant• Nameservers not on same physical subnet
– preferably with another provider
• Serial numbers YYYYMMDDnn format

• Send domain template to <[email protected]>
– an automatic mailbox
• Tool will– check assignment validity – check if zone is correctly setup– (try to) enter object to RIPE DB

Problems with inaddr Robot?
• Error report will be sent to requester– correct errors and re-send
• For questions see FAQ
• If error reports continue– contact <[email protected]>– please include the full error report

< /24 Delegations
Reverse delegation is also possible for a /24 shared by more customers
=> NOT reason for classfull assignments
• RIPE NCC reverse delegate authority for the entire /24 to LIR– procedure and requirements the same as for /24
• If customer wants to run own primary nameserver– LIR delegates parts as address space gets assigned– use CNAME to create an extra point of delegation

– for range of consecutive zones • possible also for sub-range
– represented in single inetnum object
• Shorthand notation for domain attributeinetnum: w.z.x.0 - w.z.y.255 212.73.10.0-212.73.15.255

• Submit as one domain object• Processed separately• Separate response
Local Internet Registries . Training Course . http://www.ripe.net 107
Reverse Delegation of /16 Allocation
• If a LIR has a /16 allocation, the RIPE NCC can delegate the entire reverse zone to the LIR
• Requirements and procedures the same as /24, except– /16 domain object– three nameservers needed– ns.ripe.net a mandatory secondary
• After delegation LIR– should continue to check sub-zone setup before further delegation– recommended use of the inaddr robot TEST keyword or web
check
Local Internet Registries . Training Course . http://www.ripe.net 108
Changing Delegation
• Change the nserver lines in domain object– submit domain object to <[email protected]>
• To change contact details in domain object– submit updated object to <[email protected]>
• Deleting a delegation is automatic– include delete attribute to the exact copy of the object– send to <[email protected]>

PI Request
Local Internet Registries . Training Course . http://www.ripe.net 143
PA vs. PI Assignments• Provider Aggregatable
• customer uses addresses out of LIR’s allocation
good for routing tablescustomer must renumber if changing ISP
• Provider Independent• customer receives range of addresses from RIPE NCC
customer takes addresses when changing ISP
possible routing problems
• Make contractual agreements– example: ripe-127– the only way to distinguish PA and PI space
Local Internet Registries . Training Course . http://www.ripe.net 144
Requesting PI Space
• LIR sends request on behalf of PI customer• Complete ripe-141 as usual• Differences:
#[Request Overview Template]#PI-requested: YES
#[Network Template]#status: ASSIGNED PI
• Explain why the customer wants PI – aware of the consequences?
Local Internet Registries . Training Course . http://www.ripe.net 145
Evaluation of PI Request
• Conservative estimates– will NOT get more addresses (then needed) to prevent
routing problems• Classless • Assignment is only valid as long as original
criteria remain valid (ripe-185)
• After approval– RIPE NCC assigns a block from own range– RIPE NCC puts assignment in database
with RIPE-NCC-HM-PI-MNT

Renumbering
… is easy!
Local Internet Registries . Training Course . http://www.ripe.net 148
When to Send Renumbering Request?
• Customer(s) changing providers– already using address space– returning PA addresses to OldISP – renumbering to the PA range of NewISP
• Changing from PI (or UNSPECIFIED) to PA
• Only if amount is above LIR’s AW
• Procedure made easier to encourage renumbering
• More info: http://www.isi.edu/div7/pier/
Local Internet Registries . Training Course . http://www.ripe.net 149
Renumbering Request• Complete ripe-141 request form
• Double check current addresses in DB– whois -L <customer’s IP range> => UpstreamISP inetnum– whois -m <UpstreamISP range>
• Show how addresses were used• Show how new addresses will be used
• Time frame guidelines - 3 monthsaddress-space-returned: 195.100.35/24 to UpstreamISP1 in 20010510194.200.70/24 to UpstreamISP2 in 20010701...
Local Internet Registries . Training Course . http://www.ripe.net 150
Renumbering Many Customers
• If all ‘1-1’ renumberings– include all in one request form
• making procedure easier
– separate inetnum and addressing plan for each• “50% utilisation” guideline
• If not ‘1-1’ (customer will need more addresses)– send one request per customer
Local Internet Registries . Training Course . http://www.ripe.net 151
After the Return Date
• If you are the “new” ISP for this customer– encourage your customer to renumber their whole network
to your address space
• If you are the “old” ISP of this customer– make sure you remove data from RIPE Database
• RIPE NCC hostmasters send regular reminders check ‘return’ lines in your “Reg file” data

New allocation
Local Internet Registries . Training Course . http://www.ripe.net 154
Allocation Procedures
• ‘Slow Start’– default first allocation /20
• LIR announces the whole prefix
– size of future allocations depends on current usage rate• presumably enough for next two years • not always contiguous
• Motivation for ‘slow start’– fair distribution of address space– keeps pace with customer base growth– slows down exhaustion of IPv4 address space
Local Internet Registries . Training Course . http://www.ripe.net 155
Motivation for ‘No Reservations’ Policy
• Def.: Address space set aside for future use • Reservations may never be claimed
– customers may need more (or less) address space than is reserved
• Administrative convenience not catered for
• Fragments address space =>– requesting new allocation appropriate when
previous allocated space used ~ 80% !
Local Internet Registries . Training Course . http://www.ripe.net 156
Requesting New Allocation
• Send e-mail to <[email protected]> • NOT ripe-141 form• NEWBLOCK in the subject line for higher priority
– summary of addresses assigned / free– list assignments of the last allocation
Suggested format:
Allocation: 195.35.64.0/19 assigned: 7372 free: 820 Range Netname
195.35.64.0 - 195.35.65.191 BLUELIGHT-1

Evaluation of New Allocation Request
• Are LIR’s records consistent with • RIPE NCC’s local records • RIPE database
– RIPE NCC wants to see 3 random requests
• Are all assignments valid?• within AW• correct netname attribute & the date
• Quality of RIPE DB records• up-to-date person & role objects• no overlapping inetnum objects
• Tool available: asused-public
Local Internet Registries . Training Course . http://www.ripe.net 158
Prior to Making New Allocation
• If inconsistencies are found– LIR will be asked to correct data first – AW is reviewed
• When data is corrected or deadline for correction is set– RIPE NCC
• allocates new block to LIR updates the DB
• LIR announces new prefix

Routing Registry
Local Internet Registries . Training Course . http://www.ripe.net 163
Internet Routing Registry (IRR)• Goals of the IRR
– consistency and stability of routing – enable development of tools to use information
• Local IR responsibilities– maintain policy information in RR
• Regional IR responsibilities– assigning Autonomous System Numbers– consistency checking of data– maintenance of RR support tools

IPv6
Local Internet Registries . Training Course . http://www.ripe.net 172
Why IPv6?
• Next generation protocol– scalability -- 128 bits addresses – security– dynamic hosts numbering– QoS
• Interoperable with IPv4• simple and smooth transition
– hardware vendors– applications

IPv6 Allocations
• Request form (ripe-195)• ”Slow start”
– first allocation to a TLA Registry will be a /35 block • representing 13 bits of NLA space
– additional 6 bits reserved by RIR for the allocated sub-TLA for subsequent allocations
• Reverse Delegation of an IPv6 Sub-TLA– http://www.ripe.net/reverse/
• IANA allocations– APNIC 2001:0200::/23 (23 subTLAs)– ARIN 2001:0400::/23 (12 subTLAs)– RIPE NCC 2001:0600::/23 (25 subTLAs)
