Summary

PSP Bulgaria Ltd.

Bulgaria · AI-generated

business bg small

The AS handle PSP-COMPUTERS is held by PSP Bulgaria Ltd.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname ORG-PBL21-RIPE and reverse DNS entries pointing to psp-bg.com (e.g., psp-91-230-231-64.psp-bg.com).
  • The network announces 256 IPv4 addresses within a single prefix (91.230.231.0/24) and maintains 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate endpoints and services for PSP Bulgaria Ltd., a micro-enterprise registered in the UK with operations in Bulgaria.

Notable

  • The RDAP registrant PSP Bulgaria Ltd. aligns directly with the AS holder and the reverse DNS domain psp-bg.com.
  • The address inventory is minimal, consisting of a single /24 block, which fits the profile of a small private limited company rather than a telecommunications carrier.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
