The project AS112 is a loosely coordiated distributed effort to clean up some traffic. Reverse DNS queries for addresses in RFC1918 address space are invalid, but unfortunately end up too often at the DNS root servers. Different places around the net do announce name servers (in AS112) to answer the queries, preferably close to the source.
We have created one instance at TIX and it is advertised to all peers with source AS of 112. Thus connected ISPs send those packets to the server at TIX and they get answered there instead of transiting international links.
