  1. prop-065-v001 • Format for delegation and recording of 4-byte AS numbers • APNIC26 - Christchurch NZ

  2. prop-065-v001 • This proposal recommends that APNIC changes its procedures to standardise on delegating 4-byte AS numbers in the ASPLAIN format rather than the current ASDOT format. • This proposal extends to the data recorded in APNIC Whois Database records, with the proposal recommending that whois returns the same record for queries made in either format.

  3. prop-065-v001 • ASPLAIN & ASDOT • ASPLAIN • Defines the 4-byte AS Number as a basic 32 bit integer, it is the current • format used to represent 2 Byte AS Numbers e.g. • Original 2 Byte AS pool: 0 - 65535 • New 4-byte AS pool: 0 - 4294967295 • ASDOT • Defines the 4-byte AS Number as; • <higher16bits>.<lower16bits> • e.g. • 1.4541 would be used to represent the 32 bit integer 70077

  4. prop-065-v001 • Current Problem • APNIC assigns and records 4 Byte AS numbers in the ASDOT format. • Members have never been consulted • There is no RFC for ASDOT • RIRs and IANA have adopted ASDOT with consultation (ARIN) • We now know a bit more ... • Almost all operators would prefer to use ASPLAIN

  5. prop-065-v001 • Problems with ASDOT ... • ASDOT is wildly regarded as having compatibility problems. • AS-PATH regex is broken by the “.” • ^2.37$ (matches 2137, 2237, 2337 etc) • Internal Management systems (scripts, db etc) • IRR/RPSL

  6. prop-065-v001 • ASDOT has ... • Lack of support for ASDOT in the ‘operator’ community • Issues with SNMP, REGEX, IRR/RPSL etc • ‘Canonical Textual Representation of Four-octet AS Numbers’ - Expired • draft-michaelson-4byte-as-representation-05.txt • Placing more problems in the path of 4byte adoption (bad)

  7. prop-065-v001 • Router Vendors are supporting ASPLAIN • Cisco will use ASPLAIN by default on all new code release / platforms • Juniper support ASPLAIN (9.2 will include ASDOT) • Force10 (current ASPLAIN) • Redback use “:” but moving to support ASPLAIN

  8. prop-065-v001 • What we have today • Two formats (no question here) • Operators using/preferring ASPLAIN • LIRs/Customers being allocated ASDOT

  9. prop-065-v001 • Customers will know their AS as something different • AS2.37 from the customer perspective • AS 131109 from the provider perspective • What to use for your CRM ? • What to use for the IRR/RPSL configuration • How to interact with the customer ?

  10. prop-065-v001 • Timing is critical • 1/1/09 (~4 months) will 4byte ASN are in the wild

  11. prop-065-v001 • Support • 1/1/09 (~4 months) will 4byte ASN are in the wild • If we as members want to use ASPLAIN now is the time

  12. prop-065-v001 • IETF • draft-huston-as-representation-00.txt • Strong support on the IDR mailing list • 12/14 responses supporting adoption of the draft • 13th has recently changed his opinion ?

  13. prop-065-v001 • “Having read this draft and having also previously commented on the problems the asdot/asdot+ formats create within SNMP/SMIv2 presentation, I support the adoption of this draft. “ • “The asdot/asdot+ formats will become a burden from the point of view of a network operator (specifically manipulation as subsets of strings). “ • “Having read the document, I support the asplain representation.” • “I would welcome adoption of this draft. “

  14. prop-065-v001 • IDR Updated: Enke Chen has called for the use of “::” • So now we have • . • : • :: • Integer • We in the APNIC have the opportunity to take operational matters in our hands
