Summary
One Crna Gora
mobile telecom isp infrastructure
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
/20and two IPv6/32prefixes 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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
