government municipal bulgaria

SOFIA_MUNICIPALITY is operated by Sofia Municipality.

What it's used for

  • The address space carries municipal infrastructure, identified by the netname NETERRA-SOFIA_MUNICIPLAITY-NET and registrant Sofia Municipality; Stolichna Obshtina Abuse Object.
  • The AS announces a single IPv4 prefix, 85.208.138.0/24, comprising 256 addresses, with 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal municipal services and administrative endpoints for the city of Sofia.

Notable

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
