AS12418 announces 27 IPv4 prefixes covering 68,096 addresses and 2 IPv6 prefixes.

About this network

A Russian regional provider whose reverse DNS is a list of the cities it serves.

What it's used for

• Regional access across several Russian provinces. 68,096 addresses in twenty-seven IPv4 prefixes, two IPv6 blocks, and 65 observed BGP neighbours.

Notable

• The PTR names name the city: kursk, smolensk, orel, kazan, cherep, ivanovo, ulianovsk and msk all appear as labels under ptl.ru.
• A second family of names under quantum.ru encodes the netmask instead of the place — bcast224x32, bcast248x8, bcast252x4, subnet0x4.
• Twenty-seven prefixes for 68,096 addresses. Blocks like 79.175.0.0/19 are announced whole and then again in pieces down to /24.

Interesting

• Those mask names are readable once you see the pattern: bcast224x32 is the broadcast address of a subnet whose mask ends in 224 and which holds 32 addresses, so a /27. 248x8 is a /29, 252x4 a /30. Somebody generated a zone file straight from the subnet plan, and the subnetting survives in DNS long after the router configs that produced it.
• Two names in the sample lost the dot before the city: 255.15.175.79kazan.ptl.ru. One of them also disagrees with itself, calling 79.175.23.254 an address in .22.. Generated zones fail quietly, and nothing downstream of a PTR ever checks.
