I assume quite a number of people know how to do it, especially as
several root DNS servers abuse it.
- Box with:
- Your favourite OS
- Quagga or OpenBGPd
- Your favourite DNS server
- Announce the IP of the anycast node in BGP
- Monitor the DNS server, when it does not work kill your local BGPd
and notify the admins that it broke
That is it. Probably with the above couple of things, google a bit and
find the rest.
