4. Address 128-bit long. 4x larger that IPv4 340,282,366,920,938,463,463,374,607,43 1,768,211,456 addresses Standard completed in 1996 9 of the 13 root servers have IPv6 root glue

5. Computers that are IPv6 capable Mac OS- 2.44% Linux- 0.93% Vista - 0.32% XP- 0.03%

7. Backwards compatibility In order to aid the transition from IPv4 to IPv6, current IPv4 address are being embedded into IPv6 address in a way that allows them to be recognized as IPv4 addresses by IPv6 devices.

8. IPv4-compatible IPv6 address Two types of addressing schemes to accommodate IPv4 –All zeros until the last 32 bits for devices capable of both IPv4 & IPv6 aka IPv6 aware

9. IPv4-Mapped IPv6 Addresses First 80 bits are zeros followed by 16 ones (FFFF) means that the devices whose IP address has been mapped is incapable of IPv6

11. Reserved Addresses 0:0:0:0:0:0:0:1 Anycast Link-Local Multicast

14. Interface ID Takes the MAC address and splits into 3-byte half's and between them insets ‘FFFE’ and flipping the 7 th bit of the first byte to a binary 1 in order to fulfill the 64- bit interface.

16. What’s New… Neighbor Discovery (ND) Protocol –Link-layer addresses Hop Limit Jumbogram –4.294967295 GB Stateless address autoconfiguration –Uses ICMPv6 discovery Message –Or stateful configuration using DHCPv6

17. Neighbor Discovery To determine neighbors known to reside on attached links and purge invalid values Also aids in finding routers Keep tables of reachable/unreachable neighbors and to determine any changed link-layer addresses Actively searches for alternatives if failure occurs
