Summary

Datacom

Bulgaria · AI-generated

isp hosting business

The one published hostname names a gateway, a LAN number and a datacentre city in three labels.

What it's used for

  • An internet provider in Bulgaria. 1,024 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

  • The single prefix is 195.234.236.0/22, netname DATACOM-BG.
  • One of three sampled addresses returned a name: gw03.lan060.dc-sofia.net.
  • The AS handle is DATACOM-BG-AS Internet Provider, with the business type appended.
  • One observed BGP neighbour.

Interesting

  • gw03.lan060.dc-sofia is a naming scheme with three levels of structure: the third gateway, on LAN sixty, in the Sofia datacentre. Zero-padded numbers mean the scheme was designed to sort correctly, which is a small sign of someone who had run into that problem before.
  • Publishing it means a traceroute through this network reads as a map, which helps anyone diagnosing a path and describes the topology to everyone else at the same time.
  • The domain in the reverse name is neither the company name nor the netname, so this is the third distinct identifier in a record with only one block in it.
  • One upstream on a /22 makes the provider's own connectivity a single point of failure.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
