Autonomous system
AS16344 IS-BG-AS Bulgarian ISP
Unclassified RIPE
Summary
Information Services
isp business government
The AS handle stops naming the company halfway through and starts describing it instead.
What it's used for
- A provider's network. A single IPv4 prefix announced from Bulgaria, no IPv6, four thousand and ninety-six addresses, through forty-one observed BGP neighbours.
Notable
- The AS handle begins with two initials, a country code and the letters for an autonomous system, then adds two more words that say what the company does rather than what it is called.
- The holder field gives the company's full registered name, which is two ordinary nouns and a legal form, and shares only its initials with the handle.
- The netname is a country code, the first of those two nouns, and a full date. The second noun did not fit and was dropped.
- The block lists the company and a communications department. There is no abuse role.
- Forty-one observed neighbours on four thousand addresses is a peering count an order of magnitude larger than the network it serves.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- A company named after two generic nouns is unsearchable by design, and every field in the record works around that: the handle adds a description, the netname keeps half, and the holder keeps all of it and is no clearer for it.
- A small network with many peers is the shape of somebody who interconnects for a living. The addresses are almost incidental to what the autonomous system is for.

Reputation
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 1,781 prefixes, as published 2026-10-16. 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.
