AS11965 COA-NET

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.
