Summary

INFOCOM

Bulgaria · AI-generated

business isp

One /24, one neighbour, and a netname that belongs to the national telecom rather than the holder.

What it's used for

  • A single Bulgarian network block. 256 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

  • The entire inventory is 212.72.205.0/24.
  • Its netname is BG-INFOCOMSECURITY, registered to BTC IP ADDRESS SPACE administration.
  • The AS handle is INFOCOM-AS, held by INFOCOM Plc.
  • First observed in the routing archive in September 2006.
  • Three sampled addresses were queried and none returned a name.

Interesting

  • The registrant is the address-space administration of BTC, the Bulgarian incumbent carrier, while the announcer is a separate company. That is space assigned by a provider to a customer and then announced by the customer under their own AS number, which is what a business does when it wants its routing to survive changing providers but has not gone through the process of getting its own allocation.
  • One neighbour and one /24 is the smallest viable autonomous system. There is no multihoming here and therefore no routing benefit; the AS exists so the block has an origin of its own, which matters for route objects, filters and anyone checking who announces what.
  • INFOCOMSECURITY in the netname says more about the customer than the handle does. Registry netnames are written once, by whoever filed the assignment, and they preserve the business the block was bought for long after the company has moved on.

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.
