Example

You have a properly deligated IPv6 network, for example 2001:700:300::/48.

In here you decide that you're going to use 2001:700:300:1:: for client networks, workstations and such. They usually just autoconfigured using radvd or alike.

As you have no control over what kinds of MAC addresses these clients are using (short of polling a lot of CAM (arp) -tables, which may/may not be another solution) you just have to fake it.

Here comes v6rev:

terra:~# dig 2001-700-300-1-0-0-0-1.v6.ntnu.no aaaa @localhost
[..]
;; ANSWER SECTION:
2001-700-300-1-0-0-0-1.v6.ntnu.no. 60 IN AAAA   2001:700:300:1::1

terra:~# dig -x 2001:700:300:1::1 @localhost
[..]
;; ANSWER SECTION:
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.0.0.0.0.3.0.0.0.7.0.1.0.0.2.ip6.arpa. 60 IN PTR 2001-700-300-1-0-0-0-1.v6.ntnu.no.

Or if you'd like - try it through dnsstuff.com: dnsstuff_forward and dnsstuff_back .

Basic installation

• install powerdns, with the pipe backend. (apt-get install pdns pdns-pipe)

• put the distributed files into /usr/local/v6rev/

  • install hostfunctions.py and pipe.py into /usr/local/v6bin/

• configure pdns

• deligate the reverse and forward zones of your choice

• enjoy.

warning: there are plenty of rough edges as of now. work in progress. :))
