Summary
AS112 Project
research legacy
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.
