You may want to participate in the anycast DNS cloud.

## Configuration
2013-11-04 23:12:34 +01:00
Configuration requirements for all members of the anycast group are:
* maintain your own zones based on whois database (scripts included in monotone repository)
2013-11-14 22:37:14 +01:00
* allow recursion (including `.` )
2013-11-04 23:12:34 +01:00
* 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.

### Generating Zone Files
2015-02-24 00:19:45 +01:00
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.
