About this network

An eastern Oregon network now owned by Ziply Fiber, still announcing space registered under its original name.

What it's used for

• Residential and business internet in rural eastern Oregon. A sampled address answers as 216-228-203-254.eoni.com, the domain of Eastern Oregon Net, the local provider the blocks were registered to.

Notable

• Three prefixes, 12,000 addresses, and exactly one observed BGP neighbour. This is about as minimal as an autonomous system gets while still being one.
• The AS handle is NWF-EONI-ASN-1 and the netnames are NWF-EONI-1 and NWF-EONI-2. NWF is Northwest Fiber, the company formed to buy Frontier's Pacific Northwest operations in 2020 and which trades as Ziply Fiber; EONI is the acquired local ISP. Both names are stacked into a single identifier.

Interesting

• Running an AS with one upstream is unusual — the main reason to have your own AS number is to speak BGP to more than one carrier. Here it is more likely an inheritance: the small ISP had its own AS and its own address space, the buyer kept both rather than renumbering, and the routing arrangement simplified afterwards.
