About this network

A mobile operator with eleven IPv6 prefixes against 1,792 IPv4 addresses, cut on odd boundaries.

What it's used for

• Latvia's mobile network operator. 1,792 addresses across five IPv4 prefixes and eleven IPv6 prefixes, with twelve observed BGP neighbours.

Notable

• The IPv4 inventory is 212.93.98.0/23, 212.93.124.0/23, 212.93.96.0/24, 212.93.126.0/24 and 194.125.240.0/24.
• IPv6 includes 2a03:ec00::/33 and 2a03:ec00:8000::/35.
• Netnames are LV-LMT-991124, LV-LMT, and three simply reading LMT.
• Fifteen addresses were sampled and none returned a name.

Interesting

• A /33 and a /35 are cut on odd boundaries. IPv6 is written in groups of four bits, so prefixes that are multiples of four divide cleanly and delegate their reverse zones in one piece; a /33 or /35 splits a digit down the middle and has to be delegated in fragments. Somebody halved a /32 and halved it again, taking a permanent inconvenience for a tidy internal split.
• Eleven IPv6 prefixes against five in IPv4 is the inverse of almost every network in this range. Mobile operators reached IPv6 first and hardest: handsets are numerous, they are all new enough to support it, and there was never enough IPv4 to give each one an address.
• 991124 is November 1999 in two digits, days apart from similarly stamped netnames in Poland, Turkey and Russia. The registry processed a great deal of paperwork that month and the format it used is frozen in all of it.
• Three blocks are named just LMT with no country prefix or date, next to one that has both. The unadorned ones are the oldest habit: a name only had to be unique, and the company's initials were enough.
