Summary

City of Longmont

United States · AI-generated

government enterprise

A generic label and a counter: the carrier's file for a city, not a name for one.

What it's used for

  • A municipal government's network. 256 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.

Notable

  • The whole footprint is 69.87.213.0/24, carrying the netname CITYOF-166 and registered to the city.
  • That netname names no city at all: it is the words run together, followed by a number.
  • The AS handle is COL-ETS, three initials and a department abbreviation.
  • Three addresses were queried for reverse DNS and none returned a name.

Interesting

  • The counter is the interesting field. A provider that assigns blocks to enough municipalities to need a hundred and sixty-six of them stops writing names and starts writing sequence numbers, so the label records how many customers of one kind came before rather than which one this is.
  • The registrant is the only field that identifies the holder, and the AS handle only does so if the initials are already known.
  • The trailing group in the handle reads as an internal department rather than the city itself, which is how public sector records usually arrive: the team that ordered the circuit gets named.
  • Nothing is published in the reverse DNS and no IPv6 is 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 1,849 prefixes, as published 2026-11-13. 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.
