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 intooptions/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.
