#arbitrary-dns64-generator

A PowerDNS pipe backend which synthesizes IPv4-embedded AAAA records based on the hostname being queried. There is a live instance of this code serving dns64.name (e.g. look up 192.0.2.1.dns64.name to get 64:ff9b::c000:201)

#Example usage

A query of the form:

dig 192.0.2.1.dns64.example.com ANY

Will produce the answer:

192.0.2.1.dns64.example.com. 60 IN   AAAA    64:ff9b::c000:201

This can be useful for hosts on v6-only networks where it is necessary to connect to a v4 literal for testing, or at the behest of a customer.

#Configuration

Configure in pdns.conf like so:

launch=pipe
pipe-command=/srv/dns/arbitrary-dns64-generator dns64.example.com ns1.example.com dns@example.com
pipe-regex=^(.*\.dns64\.example\.com|dns64\.example\.com)$

Where dns64.example.com is the zone to serve, ns1.example.com and dns@example.com are used to construct the SOA.
