FYI - for those scratching their heads on "anycast" .....
I just pushed out a paper on anycast by Chris Metz. Good foundation material.

Thanks - and the AS112 project seems to use static BGP spoofing, where different locations announce the address via different paths : "As a way to distribute the load for RFC1918-related queries, we use IPv4 anycast addressing. The address block is 192.175.48.0/24 and its origin AS is 112. This address block is advertised from multiple points around the Internet, and these distributed servers coordinate their responses and back end statistical analyses." Marshall

You seem to be confusing anycast with something complicated. It's not a protocol, it's a method of assigning and routing addresses.
