Summary
Carroll County Government (Maryland)
government legacy
CARR is the network of Carroll County Government, the county administration of Carroll County, Maryland, headquartered in Westminster.
What it's used for
This is a local-government network. It carries county administrative systems and the connectivity behind county services: public safety and emergency dispatch, public works, health and social services, the county's public web presence, and the office network for county staff.
Notable
Around 1,280 IPv4 addresses are announced here, a footprint that fits a mid-sized US county. Local governments are a quiet but persistent category in the routing table: hundreds of counties and municipalities run their own AS so that they can multihome, because a 911 call centre losing its upstream is not an acceptable failure mode.
Interesting
County-level ASNs are one of the more overlooked corners of BGP. They are small, they rarely change, and they are load-bearing for services that people only notice when they break.

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: 447 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.
