I have been trying to get some (virtual) IPv6 networks working with
dnsmasq acting as both an dhcp6 server and a dns server. I really do
not care how the IP6 addresses are assigned but I do want the system
names in dnsmasq's dns service so that these systems can be referred
to by name.
At some point in time I had dnsmasq actually handing out IP6 addresses
via dhcp ... or it certainly looked like that since the address was in
the range I specified. That said, I no longer know just what my
configuration was.
Basically, I am not sure I understand the meanings or effects of the
various parameters on the dhcp-range specification. Specifically, what
specifying nothing or ra-name or slaac or ra-stateless or ra-only
means .. what are the effects of each are ... or when you combine them
what happens.
I have read the dnsmasq man page but I need a little more info. It
sure would be nice to see what a working configuration looked like.
It would be nice if dnsmasq's dns service could be updated regardless
of how the address is specified (other than manually) but if only a
subset (or even one) will work ... well, that works for me too.
Yes, I searched this mailing list and found the messages saying that
you had to specify the fqdn and not just the hostname ... but that was
well after I did a lot of parameter "testing".
My next step is to take a look at the dnsmasq code to see if I can
figure things out but a few pointers and hints would be appreciated.
OK, progress. I have gotten dnsmasq to do the right thing (I belieive)
for IPv6 addresses. However, dns is not updating. I believe the reason
for that is that NetworkManager is not sending the FQDN with the dhcp6
request.
But I still have a question. Reading the man file for dnsmasq I see
that specifying "ra-names" that dnsmasq should go through this dance to
do a dns update. What needs to be specified to get that?
