  1. Introduction to IPv6

  2. 90% of this talk is stolen • I got it here • CNIT 202E, link IPv6 8

  3. IPv4 Exhaustion • Available pool is 18 "/8 address ranges" • Each /8 has 16.8 Million Addresses • 203 already allocated • 35 Reserved for special uses • Data from 5-13-2010, CNIT 202E, link IPv6 3

  4. The End is Near

  5. :: can be used once to represent a string of zeroes

  6. From Zytrax: link IPv6 10

  7. IPv6 - IPv4 Addresses • A hybrid format may be used when dealing with IPv6 - IPv4 addresses where the normal IPv4 dotted decimal notation may be used after the first 6, 16 bit address elements:

  8. Examples

  9. Multiple Addresses • Note: Interfaces normally have two addresses, or even more • Link-local FE80::w.x.y.z • Global unicast

  10. Used by Ethernet

  11. Example Interface MAC 00-40-63-ca-9a-20 IPv6 Interface ID (EUI-64) ::0040:63FF:FECA:9A20 or ::40:63FF:FECA:9A20 link local FE80::40:63FF:FECA:9A20

  12. AAAA Records in DNS • iana.org and ipv6.net work too

  13. In CNIT 202E - Link IPv6 1

  14. CNIT 202E - Link IPv6 2 (from 2003)

  15. Federal IPv6 Transition Timeline • Cisco, Sept 2009 (CNIT 202E, link IPv6 9)
