Dear Sir or Madam, Is there a working group on converging legacy protocol stacks and mapping legacy stacks addressing mechanisms into IPv6 addressing? For example, RFC 4291 & 4038 specifies that ::ffff:x.y.z.w represents IPv4 node x.y.z.w - is there a similar draft concept for specifying a Message Transfer Part point code for an SS7 stack or other telephony protocol network layer mechanisms into IPv6 addresses?
