The AS112 project is a group of name server operators in an autonomous system running anycasts instances of name servers that respond to reverse DNS queries for private addresses and private networks sent to the Internet. The distributed sink for queries sent to non-unique IP addresses helps reduce the load on the authoritative servers due to this kind of ambiguous queries by their nature which can not be answered corectly. It is named after the Autonomous System Number (ASN) that has been assigned to it.
InterLAN is one of the volunteer operators participating in the AS112 project. Anycasts prefixes of this project are advertised in InterLAN platform by a dedicated server that has peering sessions with Exchange Route Servers, this way the service is automatically available to network operators connected to these RSs.
