Summary

Baltimore County Government

United States of America · AI-generated

government municipal internal

BALTIMORECOUNTYGOVERNMENT is operated by Baltimore County Government.

What it's used for

  • The address space carries internal government infrastructure, evidenced by the netname BALTIMORECOUNTYGOVERNMENT and the registrant "Baltimore County Government; Network and Systems Manager" for 204.145.181.0/24.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative, IT, and public service endpoints for the county's municipal operations.

Notable

  • Registrants align with the announcer for the primary prefix, while 167.102.138.0/24 is registered to the "State of Maryland" under the netname NETWORKMARYLAND, suggesting state-level allocation or shared infrastructure.
  • The inventory consists of two /24 blocks, one assigned to the county directly and one to the state, reflecting a segmented internal corporate estate typical of large municipal entities.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
