I disagree to drop the second paragraph in the handling of the Rebind message.

I though the idea was to check a Rebind(/Renew) in three levels.
1. Check the client entry (Client_ID and IA ). If the it does not exist send NoBinding.
2. Check the client address with the stored address for the client. If it does not match send RebdNoMatch.
3. Check the client address with the configuration (if re-configuration has occurred during the time). If it does not match send AddrUnavail.
(All three fault cases are only valid if ALL addresses received from the client for the IA are wrong.)

If you still want to drop the paragraph, please be consistent and drop it in Renew message too.
