You may want to participate in the anycast DNS cloud.

## Configuration

Configuration requirements for all members of the anycast group are:
 * maintain your own zones based on whois database (scripts included in monotone repository)
 * allow recursion (including `.`)
 * listen on a unicast IP too for testing/debugging reasons
 * with bind, please use ```minimal-responses yes;``` (goes into ```options```/```view```)

It is _really_ good to hang around in [[IRC]] to get things sorted out, if something doesn't work. Letting some people test your DNS behavior before joining the anycast-group is considered best practice - better safe than sorry.

 * **IP:** 172.22.0.53
 * **Announciation Subnet:** 172.22.0.53/32

### Generating Zone Files

There are a few different scripts for generating zone files. They have been written in a few different languages. Please keep in mind that RFC 2317 is what keeps people from registering a /24 _just to have RDNS_, so scripts that support it have a positive effect on address space usage.
