About this network

A national operator whose reverse names are generated from the address, except for the one that isn't.

What it's used for

• The national telecommunications operator of Kyrgyzstan. 82,944 addresses across 15 IPv4 prefixes, one IPv6 prefix, and three observed BGP neighbours.

Notable

• Every block carries a KG-KT- netname with its date: 20050202, 20060713, 20080522, 20090529, 20101206, 20110302 and 20120402.
• Twelve of eighteen sampled addresses returned names, nearly all matching their own address, as in 37-218-159-255.pppoe.ktnet.kg.
• One does not: 89.237.223.255 answers with 213-145-223-255.pppoe.ktnet.kg.

Interesting

• That mismatch is the interesting thing in this record. Every other name encodes the address it belongs to, and this one encodes a different address entirely, in a range the operator does not announce here. The zone was generated once for space that has since been renumbered, and the stale records were carried across rather than regenerated. Anyone using reverse DNS to identify an address would be told the wrong network.
• pppoe names the access protocol in every hostname, which dates the subscriber technology as clearly as any netname does. It is a dial-up-era protocol carried forward onto broadband lines, and operators keep it because the billing and authentication systems are built around it.
• Seven dated netnames from 2005 to 2012, one every year or two, is a national operator growing steadily through the period when address space was still obtainable.
• Three neighbours carrying a country's internet. Landlocked markets depend on transit through their neighbours, and that constraint is visible directly in the neighbour count.
