Summary

Bulgarian National Bank

Bulgaria · AI-generated

government business finance

The AS handle BNB is held by Bulgarian National Bank.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname BNB-NET and registrant Bulgarian National Bank.
  • The network announces 256 IPv4 addresses within a single prefix (91.209.146.0/24) and maintains 2 observed neighbours, indicating a small, self-contained internal estate rather than a transit or access provider.
  • Traffic from this AS consists of internal office workers and financial system endpoints for the central bank of the Republic of Bulgaria.

Notable

  • The RDAP registrant Bulgarian National Bank and netname BNB-NET align perfectly with the AS holder and the registry name.
  • The address inventory is a single /24 block, representing a compact and finely managed corporate network segment.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
