AS112 — AS112-PROJECT

AS112 announces 2 IPv4 prefixes covering 512 addresses and 2 IPv6 prefixes.

About this network

The AS112 Project (AS112-PROJECT), a cooperative, volunteer-run anycast service that absorbs reverse-DNS and other queries for private and otherwise non-routable address space so they don't burden the root and public DNS.

What it's used for

• Answering reverse-DNS (PTR) and dynamic-update queries for RFC 1918 private ranges and similar special-use address space, as a distributed sink.

Notable

• Not an organization's network at all: many independent operators run AS112 nodes worldwide under the same AS number, using anycast. The low AS number fits its long history as early internet infrastructure.

Interesting

• A rare case where the same AS number is deliberately announced from many unrelated networks around the globe.
