Unclassified ARIN
Summary
City of Aspen
government legacy
COA-NET is the municipal network of the City of Aspen, the local government of Aspen, Colorado. ARIN records the ASN to the city at 130 S. Galena St., Aspen, CO — the municipal building address.
What it's used for
- Municipal government connectivity: the city's own internet-facing services and administrative network, announced as a single
/24(256 addresses) of ARIN space registered to the City of Aspen itself. - The registrant of the prefix and the holder of the ASN are the same organization, so this is first-party space rather than an ISP announcing a customer's block. There is no sign it carries anyone else's traffic.
Notable
- The routing footprint is exactly what a small-town government looks like in BGP: one prefix, two observed neighbours. That neighbour count is the useful signal — a transit carrier of any size peers with hundreds of networks, while an organization that simply wants two upstreams for redundancy shows a handful. Aspen runs an AS because it wants multihomed resilience for city services, not because it sells connectivity.
Interesting
- The low AS number is misleading. ARIN registered this ASN to the city in 2017, so it is a reissue of a number freed from an earlier holder, not a survivor of the early internet. Numbers in the AS11000s have been recycled heavily, and the current holder is what matters.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
