Hi Swetha, Thanks for sending this to 6man.
One concern I have with this document is that it introduces a completely new and completely separate way to perform address and prefix assignment, which are already well supported in IPv6. SLAAC and DHCPv6 are extremely widely deployed and provide most or all all the functionality that is described here. If we introduce new standards then we will be requiring implementers and standards developers to do more work, which all else being equal is likely to result in lower quality implementations, lower interoperability, and potentially larger code size. So - do we really need these new address assignment methodologies? And how many hosts will need them? For example, for prefix delegation the draft says that DHCPv6 "remains inefficient from an energy and bandwidth consumption viewpoint", but it does not provide any evidence to support that statement. What is inefficient about DHCPv6? At best, DHCPv6 can be a single-RTT exchange with lifetimes as long as 2^32 seconds (136.1 years), and that seems quite efficient.
