  4. Unique Identifiers on the Net • Behind every transaction on the net is a maze of technical identifiers to help the packets move around. • Domain Names (human readable names) • Autonomous System Numbers (routing) • IP addresses (Both IPv4 and IPv6) • Many other Identifiers • http://www.iana.org/numbers.html

  5. Uniqueness • For the Internet to function as we know it uniqueness of these identifiers is a prerequisite. • Users want to know that an e-mail going to john.crain@icann.org goes to me and not to a different John Crain at a different ICANN.

  6. Global Registry • To enable this uniqueness technical identifiers for the Internet are registered at ICANN via the IANA function. • Internet Corporation for Assigned Names and Numbers • http://www.icann.org • Internet Assigned Number Authority • http://www.iana.org

  7. IP Address Allocations and Assignments ICANN (IANA function) ICANN distributes blocks to Regional Internet Registries AFRINIC APNIC ARIN LACNIC RIPE RIRs allocate IPs to Local Internet Registries and ISPs LIR NIR ISP ISP LIR LIR LIR LIR LIRs assign addresses to their end users, businesses or smaller Internet Service Providers business small ISP end user end user

  8. Policy development is Bottom Up • Policies are proposed and refined within the various policy groups that are enabled via the Regional Internet Registries. • http://www.apnic.net These discussions are open to you!! Global policies are ratified by the ICANN Board

  9. IPv6 in the DNS • In the Internet people type in domain names: • http://www.icann.org, john.crain@icann.org • Computers use the IP addresses. • Translation occurs in the DNS (Domain Name System) • In IPv4 the DNS record is called an “A” record • In IPv6 the DNS records is the “AAAA” record www.icann.org. IN A 192.0.34.163

  10. IPv6 in the DNS • AAAA records added to the root zone for Top Level Domains • Next step is to add them for the root servers themselves. This should occur in 2006. Until this occurs we cannot fully resolve names to IPv6 addresses.

  11. Who remembers CIDR? • Classless Inter-Domain Routing • Early ‘90s through mid ‘90s • Changed from set size subnets (A,B,C) to varying subnets. • Painful experience!! • Gateways/Routers needed to be modernized. • Many providers waited until the last possible moment to update equipment. • It took years, some people still think and operate classfully.

  12. How is IPv6 different + No looming day for change: * If you start planning now we still have x years of IPv4 address space to distribute. • Changes go further: • This is not the same network as when we went to CIDR.. • We have to design for long term interoperation with IPv4

  13. IPv6 is it real? • Yes! • It is in use on networks today. • At the moment the network is mainly IPv4 with islands of IPv6. Over time that will turn to where we have islands of IPv4 in an IPv6. • Even if you don’t need the added functionality we do need the increased address pool.

  14. Be Ready!!! • Even if you don’t plan to migrate tomorrow make sure that your planning takes into account the future need for IPv6 support. If you start preparing now then the pain of change will be much lessened in the future. This is not rocket science, it’s common sense!

  15. It is not if you are going to convert to IPv6. • It is when you are going to IPv6 Be Ready!!!
