Client domain in FQDN option

[Greg.Rabil at ins.com]

I have a question regarding the domain used for Dynamic DNS updates.  If I read the man page (and the code) correctly, it appears that the domain portion of the FQDN determined by the server is always taken from either the configured domain-name option (15) or the ddns-domain-name policy.  The hostname portion of the FQDN is derived from either the hostname option (12) supplied by the client or the leftmost label of the FQDN option (81).  That is, any domain provided by the client in the FQDN option (81) is essentially ignored by the server when performing the DDNS update.

1.  Is that correct?
2.  If so, that does _not_ violate section 4 of RFC 4702, as all references therein related to this are defined as MAY.  However, I was simply wondering if there was any plans to support additional behavior in the server to use the client's notion of the domain, or if there are any other workarounds that may be available.

Thanks,
Greg Rabil
