Hi, Gaurav,

Thanks for your carefully review. Reply in lines. With all your comments addressed, would you support this document forward?
[Gaurav] Certainly. I support the document forward.

Reworded: This document introduces a new DHCPv6 procedure to configure hosts' IPv6 addresses. In this new procedure, the prefix is advertised from a DHCPv6 server through DHCPv6 protocol while the interface identifiers are independently generated by the hosts.

All changed.

Have added a sentence for this. However, this is only a MAY. "A host MAY include a Option Request Option in a Solicit or Request message to request a IA_PA explicitly." The prefix assignment could be in advertise model. It is not necessary that a host request a IA_PA.
[Gaurav] I don't understand this part completely. So you are saying that host can send "DHCP REQUEST" message as well instead of SOLICIT.? Can you please elaborate it in detail.

Request message is possible, too. See the above new sentence.

[Gaurav] I was referring to "Information-Request(11)" message not  "Request(3)"


>7.) What should the host do after timers expire.? And is the DHCPv6

Have added two sentences in Section 4 to describe the potential follow up operation: 

When the host reaches T1 or T2 defined in Section 5.1, it SHOULD use the same message exchanges, as described in section 18, "DHCP Client-Initiated Configuration Exchange" of [RFC3315], to obtain or update prefix(es) from a DHCPv6 server.

A DHCPv6 server MAY initiatively send a reconfiguration message to the host, as described in section 19, "DHCP Server- Initiated Configuration Exchange" of [RFC3315], to cause prefix(es) information update.

Best regards,

Sheng
