My environment: RedHat Fedora Core 12 x86_64
BIND version: bind-9.6.1-11.P1.fc12.x86_64
Let’s see an example how to configure IPv6 reverse lookup record in BIND.
Forward Lookup:
www AAAA 2001:123:45:678:20c:29ff:fe6a:7f93
It just like normal IPv4 host record, except it is a “AAAA” record instead of an “A” record.
Reverse Lookup zone configuration in named.conf:
zone "8.7.6.0.5.4.0.0.3.2.1.0.1.0.0.2.ip6.arpa" {
type master;
file "2001.123.45.678-db";
};
The name of the zone is the reverse of the /64 prefix 2001:123:45:678::/64
In the reverse lookup zone file, the PTR record is:
3.9.f.7.a.6.e.f.f.f.9.2.c.0.2.0 IN PTR www
The PTR record is the reverse of the host portion of the IPv6 address.
Try a dig -x 2001:123:45:678:20c:29ff:fe6a:7f93 and see if the BIND server replies with the reverse lookup record correctly.
