<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>Yes, I have all the
settings you’ve identified below. And yes, dynamic DNS updates work
just fine as soon as I comment out the “option server.ddns-*” lines
from dhcpd.conf. Of course, then the updates occur using the hostname
from the client and the configured option domain-name value. I have tried
with both the 3.0.6 and 3.1.0 servers with a client that sends the FQDN option
both in ASCII and binary encoding. Consistently, as soon as I add the
“option server.ddns-*” settings, no dynamic DNS updates are even
attempted.<o:p></o:p></span></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>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.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>1. Is that correct?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>2. If so, that does _<i>not</i>_
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.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thanks,<o:p></o:p></span></p>
