Re: Format of the IPv6 reversed zone
There is a little perl ipv6 calc that I use ipv6calc so I don't mis-typo it. ipv6calc --addr_to_ip6arpa 2001:1930:c00::2 No input type specified, try autodetection...found type: ipv6addr 2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.c.0.0.3.9.1.1.0.0.2.ip6.arpa. The web page is dead, but the ftp download works. http://mirrors.bieringer.de/www.deepspace6.net/projects/ipv6calc.html#id2860191 and of course one can easily run a script to spit out the reverses.

I have '2001:42a0::/32', in 'named.conf - I have...
zone "0.a.2.4.1.0.0.2.ip6.arpa" {
type master;
file "pri/db.0.a.2.4.1.0.0.2.ip6.arpa";
};
Top of the file could look like
$TTL 7200
@ IN SOA blah. usual stuff..
Then - networks are all /64's - so - using the $ORIGIN variable...
do something like this per network
; 2001:42a0:0:ff02::/64, Some description of this network
$ORIGIN 2.0.f.f.0.0.0.0.0.a.2.4.1.0.0.2.ip6.arpa.
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 IN PTR cisco.posix.co.za.
2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 IN PTR dns1.posix.co.za.
or simply delegate them off
; 2001:42a0:1:82::/64, another network
2.8.0.0.1.0.0.0.0.a.2.4.1.0.0.2.ip6.arpa. NS dns1.posix.co.za.
NS dns2.posix.co.za.
'dig -x' is your friend for expanding the address!
eg - dig -x 2001:42a0:1:82:: +noall +question
...then cut'n'paste!
