AS112 Service

INEX operates an AS112 server.  This system provides anycast reverse DNS lookup for several prefixes, namely:

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

Because these IP addresses are widely used for private networking, many end-user systems are configured to perform reverse DNS lookups for these address ranges.  DNS lookups for these ranges should always be null-answered quickly, in order to make sure that DNS retransmits don't occur (thereby overloading local DNS resolvers), and to prevent end-user systems from hanging due to DNS lookups.

AS112 services are provided around the world by a group of volunteers.  

Connectivity to this service is available to all INEX members at no charge.  To avail of this service, please contact INEX operations, and we will set up a BGP peering session on the INEX AS112 server. INEX's details are:
