Summary

City of Mesa

United States of America · AI-generated

government municipal network

AS19185 is operated by the City of Mesa, the municipal government of Mesa, Arizona.

What it's used for

  • The address space is registered under the netname NETBLK-MESAAZ for the City of Mesa, indicating internal municipal infrastructure.
  • The AS announces 2560 IPv4 addresses across 2 prefixes (199.101.32.0/21 and 199.101.40.0/23) with only 2 observed neighbours, a ratio consistent with a self-contained government network rather than a transit or access provider.

Notable

  • Both announced prefixes are registered to the City of Mesa via ARIN, matching the AS holder.
  • The inventory consists of two contiguous IPv4 blocks with no IPv6 prefixes announced.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
