Learning IPv6

IPv6 is not new to me but .. i didnt remember anything about it. So i should re-learn it every day to help my mind remember it. hehe.

Here is my notes:

Local address: fecX/fedX/feeX/fefX
Unicast Address:  fdXX/fcXX (This is new defination)
Global Unicast: 2XXX/3XXX
6bone: 3ffe
6to4: 2002
ISP: 2001
Multicast: ffXY
ffx1: node-local, packets never leave the node.
ffx2: link-local, packets are never forwarded by routers, so they never leave the specified link.
ffx5: site-local, packets never leave the site.
ffx8: organization-local, packets never leave the organization (not so easy to implement, must be covered by routing protocol).
ffxe: global scope.
others are reserved
