Summary

Clark County, Washington

United States of America · AI-generated

government county network usa

CLARKCOUNTYWA is the autonomous system for Clark County, Washington.

What it's used for

  • The space carries government infrastructure, evidenced by the reverse DNS record host187254.clark.wa.gov and the registrant netname CLARKCOUNTYWA.
  • The AS announces a single IPv4 prefix, 64.4.176.0/20, comprising 4096 addresses, with one observed neighbour. This low neighbour count relative to the address block indicates an internal government network rather than a transit provider.

Notable

  • The RDAP registrant Clark County WA; Network Administration aligns perfectly with the AS handle and the reverse DNS domain clark.wa.gov.
  • The address inventory consists of a single contiguous /20 block, typical for a municipal or county government network managing its own internal services and connectivity.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
