I'll second that, and add that it would be nice if there were some
commonality* between the ip4 and ip6 servers - that way us poor
sysadmins wouldn't have to learn yet another totally new bit of
software (just learning to admin IP6 could be enough fun for one day).
* Yes I know there's a lot of differences, but I'm sure there's a lot
of common stuff as well. Little details like not having a virtually
identical config structure EXCEPT for needing quotes in slightly
different places (cf dhcpd vs bind) !
Random thoughts that come to mind (as someone who hasn't used ip6
yet) include :
Could they share a common config file ? Or are they best kept as
completely separate entities ?
Would it be easier for sysadmins to do some intelligent stuff, or
keep separate options ? Eg, would it be better to have :
option domain-name-servers=dns0.domain.com;dns1.domain.com;
option domain-name-servers6=dns60.domain.com;dns61.domain.com;
or just :
option domain-name-servers=dns0.domain.com;dns1.domain.com;
and the server take care of only giving ip4 address with ip4 leases,
and ip6 addresses with ip6 leases ? I'm assuming in this latter case
that dns0.domain.com might resolve to a.b.c.d in ip4 space, and
1234:5678::90ab in ip6 space for example.
Supplemental to that, how will the current server behave if resolving
a fqdn returns both an A and an AAAA record ?
How do dual-stack machines handle resolver config ? Do they have a
separate config for the IP6 stack, or else how do they manage two
separate dhcp clients playing with one config file ?
How are multiple ip6 leases managed, I believe multiple addresses are
a standard feature of IP6 ? How does that fit in with changes
planned/under way with the current server and how it handles client
identity ?
