radvd, BIND and DHCP

OK, a little query here. Been trying to get an answer all over the place,
but no examples of how to set this up, so I haven't been able to work it
out myself.

Hope someone can help.

I have a server which has BIND and DHCP on it.

With IPv4, I can have a client attach as "Arthur" and the DNS entries will
be updated automatically. I can then ping Arthur using its name from all my
machines on my small network.

How do I do this with IPv6? Or is the reason I am not getting the answer
because it isn't necessary?

I.e. I want to use IPv6, which I can set up with radvd running on the
server. However, how do I get DNS to update the A6 records? Without that, I
cannot ping6 arthur, I have to ping6 3ffe:109a:f45:93e3:... Not so easy.

Cheers.

Surely part of the answer is that with V6 you do not use DHCP, the address
is built of two parts, the network address and the MAC address of the
network card. So as long as your machine stays on the same network it
will always have the same address, and the DNS entry remains valid.

This is called Dynamic DNS, by the way.

You _can_ still use DHCP with IPv6, its just that you don't need to, and
I don't think there is much in the way of support for it.

If you read the IPv6 RFCs, you'll notice that there are two types of
auto-configuration, stateless and stateful. Stateless autoconfiguration
uses router advertisements (ie. radvd). Stateful autoconfiguration uses
DHCP, though I don't think that avenue is much developed at the moment.

The two _are_ different however. I suspect both will have their places
when IPv6 becomes mainstream.

Thanks. I am pretty much convinced that radvd replaces DHCP, but there is no
documentation on DDNS and IPv6. ALL of the documentation about DDNS updates
is about using DHCP and IPv4. Quite annoying.

Can anyone fill in the blanks? Or is DDNS not used for IPv6?!?!
