Unclassified ARIN
Summary
County of Henrico
government municipal virginia network
HENRICO-AS is the autonomous system operated by the County of Henrico, a local government entity in Virginia.
What it's used for
- The address space is registered under the netname
HENRICO-GENERAL-GOVERNMENT, indicating it supports the county's internal government operations and infrastructure. - The AS announces 3840 IPv4 addresses across 4 prefixes with only 2 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or large-scale access provider.
Notable
- All four announced prefixes share the same registrant,
County of Henrico, confirming the address space is owned and managed directly by the government entity. - The inventory consists of four contiguous IPv4 blocks within the 173.242.0.0/16 range, with no IPv6 prefixes currently announced.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-17, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
