  2. Schedule • Requesting Address Space • Introduction to RIPE NCC • Global Registry System • Initial Administrivia of Becoming LIR • First Request • Completing the request form • Communication with hostmasters • Customer’s Request • Elementary evaluation • RIPE Database • Evaluation of specific assignment cases • Large request • PI request • Renumbering • Assignment Window • New allocation

  3. Introduction to RIPE NCC

  4. 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

  5. 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 • 62 staff (22 nationalities) • 2,018+ participating Local IR’s • 11,390,000+ countable hosts in the RIPE NCC region • 3,041,650+ objects in the database

  6. RIPE NCC Activities (1) Member Services • Registration Services • IPv4 addresses • IPv6 addresses • AS numbers • LIR Training Courses • <hostmaster@ripe.net> • Reverse domain name delegation • NOT registering domain names

  7. RIPE NCC Activities (2) Public Services • RIPE database maintenance • Routing Registry Maintenance (RR) • Co-ordination • RIPE support • Liaison with: • LIRs / RIRs / ICANN / etc … • Information dissemination • New Projects • Test Traffic Measurements • Routing Information Service (RIS) • Routing Registry Consistency (RR)

  8. RIPE Database (1) • Public Network Management Database • Information about objects IP address space inetnum, inet6num reverse domains domain routing policies route, aut-num contact details person, role • Server whois.ripe.net • UNIX command line queries • http://www.ripe.net/ripencc/pub-services/db/

  9. RIPE Database (2) • Software Management • server and client • NOT relational • 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

  10. Summary: RIPE & RIPE NCC Two separate organisations, closely interdependent • RIPE • open forum for discussing policies • RIPE NCC • legitimate, not-for-profit association • formal membership • neutral and impartial

  11. Questions?

  12. Terminology • Global Registry System

  13. Terminology • Allocation • address space given to registries which is held by them to assign to customers • Assignment • address space given to end-users for use in operational networks /20 allocation = 4096 addresses assignment assignment

  19. Questions?

  20. Initial Administrivia of Becoming LIR

  21. Becoming LIR • Completed application form (ripe-212) • Provided Reg-ID & contact persons • <new-lir@ripe.net> • Read relevant RIPE documents • Signed contract (ripe-191) • agreed to follow policies and procedures • Paid the sign-up & yearly fee • <billing@ripe.net>

  22. Contact Persons • Stored in RIPE NCC internal file for each registry • confidential • Only registered contact persons can • send requests to hostmasters • change contact information • PGP optional (soon) • Use ‘role’ object • for multiple admin-c and tech-c • Members’ mailing lists • <local-ir@ripe.net> • <ncc-co@ripe.net>

  23. Registry Identification (RegID) • Distinguishes between contributing registries and individuals • Format • <country code> . <registry name> • Include with every message • Suggestion - modify mail header • X-NCC-RegID: nl.bluelight

  24. Questions?

  25. New Registry’s First Request • Completing the request form • Communication with the hostmaster

  26. Sample First Request • Example: Blue Light Internet • LIR wants a block of IP addresses • e.g. for own network / infrastructure • do not include needs of customers yet Steps: • Complete request form ripe-141 • Send request to <hostmaster@ripe.net> • RIPE NCC evaluate and approve request With first assignment LIR automatically receives /20 allocation

  27. Request Formripe-141 I. General Information Overview of Organisation Contact Information Current Address Space Usage II. The Request Request Overview Addressing Plan III. Database Information IV. Optional Information

  28. Completing the Request Form (starting from Addressing Plan)Gathering Information • Design of the network • how many physical segments it will consist of • what is each segment going to be used for • including equipment used • how many hosts are in each segment • expectations of growth

  34. Communication with <hostmaster@ripe.net>

  35. Ticketing System • Unique ticket number • facilitates retrieval / archiving • NCC#YYYYMMXXXX • e.g. NCC#2000053280 • Check status of ticket on the web • http://www.ripe.net/cgi-bin/rttquery • open ncc • open reg • closed

  36. Hostmaster-robot • Checks request form • Reg-ID, contact persons • syntax • policy problems • Acknowledgement & diagnostics • LONGACK • Error message • correct & re-send the request • use same ticket number • NOAUTO • No errors: hostmaster wait-queue • “ongoings” directly to hostmasters

  37. Request Approved • With the first ASSIGNMENT approved LIR automatically gets an ALLOCATION • /20 (4096 addresses) • Hostmaster enters allocation and assignment objects into the RIPE database at this time • /24 & /25 & /26 instead of /23 • Whole allocated range can be announced immediately • Every request has to be sent for approval to RIPE NCC • addresses for LIRs own infrastructure • all customers’ request

  38. Questions?

  39. Customer’s Request Evaluation Basic Database Issues

  40. Assignment Process Gathering information Completing ripe-141 Customer no Documentation completed? yes RIPE NCC evaluation no Documentation completed? approval notify customer update local records update RIPE database  Assignment

  41. Gathering Information • One request form per customer • Ask the same questions RIPE NCC asks LIR • enough information to complete ripe-141 • Add comments • Example: Goody 2 Shoes

  42. Before Submitting the Request • Syntax check the request on the Web • Complete documentation reduces need for iteration • All the data communicated with RIPE NCC is kept strictly confidential • Documentation for RIPE NCC has to be in English

  43. Evaluation -- General Information • #[Overview of organisation template]# • information relevant to the address space request • Name and location of the company? • What are the company activities? • What is the structure? • Does it have subsidiaries and where? • For what part of the company are the addresses requested? • #[Requester Template]# • LIR contact for RIPE NCC • #[User Template]# • customer’s contact for LIR

  44. 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?

  45. Evaluation -- Network Template • inetnum value • specifies the size of assignment • actual range is not necessary • Relevant netname • 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

  46. Assignment for customer’s network Assignment for LIR’s network Internal Administration • Wait for approval from <hostmaster@ripe.net>prior to assignment and registration • Decide on the range of within your address space • classless assignment on bit boundary • Update local records • archive original documents with assignment

  47. Creating Database Objects

  48. 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 <auto-dbm@ripe.net> • Each person object has unique nic-hdl

  49. whois -t person person: [mandatory] [single] [primary/look-up key] address: [mandatory] [multiple] [ ] e-mail: [optional] [multiple] [look-up key] phone: [mandatory] [multiple] [ ] notify: [optional] [multiple] [inverse key] nic-hdl: [mandatory] [single] [primary/look-up key] changed: [mandatory] [multiple] [ ] source: [mandatory] [single] [ ]

  50. nic-hdl • Mandatory attribute • Only way to clear ambiguity in person objects • Format: <initials><number>-<regional registry> • e.g. AB123-APNIC, CD567-RIPE • Combination of person nameandnic-hdl is the primary key for person object • Use “AUTO-#” placeholders person: Piet Bakker ... nic-hdl: AUTO-1 person: Jan van der Bruk ... nic-hdl: AUTO-#initials PB1234-RIPE AUTO-1JVDB JVDB1-RIPE
