Summary

City of Hayward

United States of America · AI-generated

government municipal network

CITYOFHAYWARDCA is operated by the City of Hayward.

What it's used for

  • The address space carries municipal infrastructure, evidenced by the registrant City of Hayward and netname SBCIS-101216-125253.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small internal government network rather than a transit or access provider.

Notable

  • The RDAP registrant City of Hayward aligns directly with the AS holder CITY OF HAYWARD.
  • The inventory consists of a single /24 block (64.172.103.0/24), indicating a compact, self-contained address estate typical of a municipal utility or city hall network.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
