Are you creating DNS entries somehow (reverse and, ultimately, forward), are you using BIND "generate" statements, are you using wildcards...or are you just ignoring this for the "dynamic boxes"?
I haven't had my coffee yet this morning, so I may be misunderstanding you... I think you're asking for some way for your v6 subnet to both have proper forward and reverse DNS, right? If so, I personally find http://member.wide.ad.jp/~fujiwara/v6rev.html very useful. If you run a "normal" DNS server on the same IP, it probably will be hard to get it working. But, if you don't, it's pretty easy. You'd want to get v6rev.pl from the page above. Here is my config example: server_address: 0.0.0.0, 2001:470:892c:3432::1 server_port: 53 pid_file: /var/run/v6rev.pid reconfig_interval: 3600 reverse_domainname: c.2.9.8.0.7.4.0.1.0.0.2.ip6.arpa #/48 tbroker home reverse_domainname: 1.0.8.c.0.7.4.0.1.0.0.2.ip6.arpa #/48 tbroker work forward_domainname: dyn.harry.lu keyfile_dir: /home/v6rev/keys ttl: 3600 nsname: dyn.harry.lu enable_dnssec: 0 querylog: 1 static_ptr: 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.3.4.3.c.2.9.8.0.7.4.0.1.0.0.2.ip6.arpa harry.lu static_ptr: 5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.8.c.0.7.4.0.1.0.0.2.ip6.arpa staticsample.harry.lu Now, if you check the forward and reverse DNS entries for the subnets you defined in reverse_domainname: $ dig -x 2001:470:892c::7 +short 20010470892c00000000000000000007.dyn.harry.lu. $ dig AAAA 20010470892c00000000000000000007.dyn.harry.lu +short 2001:470:892c::7 Pretty cool, eh? You can also add in your own static ones on the same subnet using static_ptr. However, I bet I totally misunderstood your question!
