Public Service: AS112 - RFC1918 PTR Zones

Quote from the AS112 Project Home Page:

Because most answers generated by the Internet's root name server system are negative, and many of those negative answers are in response to PTR queries for RFC1918 and other ambiguous addresses, as follows:

• 10.0.0.0/8
• 172.16.0.0/12
• 169.254.0.0/16
• 192.168.0.0/16

There are now separate (non-root) servers for these queries...

Some other zones, such as similar IPv6 reverse zones, are also being added to the AS112 service.

TREX hosts an instance of the AS112 anycast servers. Members can get access to them by peering with TREX's BGP routers and/or route servers and accepting the following routes from them:
