IPv6: Difference between revisions

Prefix Delegation doesn't *always* return a /64 - it could be a /60 or the /48

===LAN /64 (or larger) Blocks===
 
We also respond to DHCPv6 Prefix Delegation (Option 25, Identity Association for Prefix Delegation, responded to by Option 26, IA Prefix) from the CPE and we'll tell the CPE one of the /64IPv6 Blocks. (the lowest numbered one) - this may be requested multiple times by the CPE (each time with the next highest numbered block). The delegated block can be the /48, or a /60, or a /64.
A Client Identifier (Option 1) is also present in the DHCPv6 transaction, optionally DNS recursive name server (Option 23) can be requested.
 
At this point we will be routing any IPv6 blocks to your /128 WAN address. Usually a line will have at least one /64 block routed.
 
Customers can add additional /64 blocks or /60 blocks on the Control Pages that will be routed.
 
If you want the whole /48 routed, untick the routing on all of the /64s and /60s you have, they disappear, and then tick the line routing on the /48 you have. Alternatively Support staff can help.
 
Your router will have to reconnect to AAISP before the new block is routed to your /128 WAN address. You will have to allow the new block through any firewall you have, and then route the new block appropriately on your local network.
