Summary

City of Des Moines

United States of America · AI-generated

government municipal network

The AS handle CDM-AS is held by the City of Des Moines.

What it's used for

  • The address space carries municipal infrastructure, evidenced by the netname CDM-11 and registrant City of Des Moines associated with the prefix.
  • The AS announces 512 IPv4 addresses within a single prefix (104.225.248.0/23) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained government network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant City of Des Moines aligns perfectly with the AS holder and the registry name CDM-AS.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a compact internal estate for city 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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
