>Description:
RFC3152 concerns the delegation of IP6.ARPA. as the top level domain
for inverse lookups of IPv6 addresses. It states, in part:
2. Obsoleted Usage
This document deprecates references to IP6.INT in [RFC1886] section
2.5, [RFC2553] section 6.2.3, [RFC2766] section 4.1, [RFC2772]
section 7.1.c, and [RFC2874] section 2.5.
In this context, 'deprecate' means that the old usage is not
appropriate for new implementations, and IP6.INT will likely be
phased out in an orderly fashion.
Note that the default /etc/namedb/named.conf supplied with
FreeBSD contains:
zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.INT" {
type master;
file "localhost-v6.rev";
};
whereas the bind 8.3.x software bundled with the system observes the
new usage, so that:
dig -x ::1
generates a query like:
;; QUERY SECTION:
;; 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa, type = ANY, class = IN
>How-To-Repeat:
>Fix:
For backwards compatibility, just add the ...ip6.arpa zone to named.conf:
happy-idiot-talk:/usr/src:# diff -u etc/namedb/named.conf{.orig,}
