Summary

City of Henderson

United States of America · AI-generated

government municipal network

The AS handle COH is operated by City of Henderson, Nevada.

What it's used for

  • The address space carries municipal infrastructure, evidenced by the netname COH-240-DMZ-01 and the registrant City of Henderson, Nevada.
  • The network announces 1024 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of city government services, public works infrastructure, and administrative endpoints for the municipality.

Notable

  • The registrant City of Henderson, Nevada aligns directly with the AS holder and the COH handle.
  • The inventory consists of a single contiguous /22 block (205.174.28.0/22), representing a compact and unified address estate for the city's digital operations.

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 1,779 prefixes, as published 2026-10-22. 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.
