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.

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
