AS15397 — TELENORMONTENEGRO
AS15397 announces 1 IPv4 prefixes covering 4,096 addresses and 2 IPv6 prefixes.
About this network
The AS handle is the old owner's brand run together into one word.
What it's used for
- A mobile and fixed operator. One IPv4 /20 and two IPv6 /32 prefixes announced from Montenegro, four thousand addresses, across ten observed BGP neighbours.
Notable
- The handle is a former parent company's name and the country's name with no separator between them, seventeen letters in a row.
- The netname repeats that former brand with the country code and the allocation date, so two of three identifiers name a company that no longer owns the network.
- Only the registrant carries the current name, alongside the old one on the same line.
- Two IPv6 allocations of the standard size against a single IPv4 block.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- European mobile operators change hands often, and the registry is the last place the old brand survives. Renaming an AS handle means coordinating with a registry for no operational gain, so it waits forever.
- Two IPv6 allocations usually means two former companies merged, each bringing its own. That fits what the names say.
- Ten neighbours for four thousand IPv4 addresses is a well connected operator whose subscribers sit behind address translation rather than on public addresses.
