I wonder whether DHCPV4REQUEST and DHCPV4REPLY (perhaps with a hyphen) may actually be better choices for the V6 messages. While the underlying protocol is BOOTP, that name is somewhat misleading and most everything now uses DHCP[v4] -- yes, I know that I was likely the source of those original message names.

I'm not sure using QUERY/RESPONSE adds much value.

But again, I really have no good answer here and was not trying to promote one name over the other - I was just asking the WG the question as to whether these are good message names or whether we wanted to change them now, before we are stuck with them 'forever'.

It is a minor issue (as what goes over the wire is really a message type code), but it does make a difference in tools (i.e., packet decoders), logs, and in source code.

The only reason to use BOOTREQUESTv6 and BOOTREPLYv6 is the similarity between that name and the name of the BOOTP packet that DHCPv4 rides in.   If you are going to change the name, you might as well call it DHCPv4QUERY and DHCPv4RESPONSE or something.   Using the BOOTP name allows you to avoid confusion between DHCPREQUEST/DHCPREPLY and DHCPv4REQUEST/DHCPv4REPLY, but you could use QUERY/RESPONSE to avoid that just as well.

Anyway, I don't think BOOTPREQUESTv6 makes a whole lot of sense.
