Summary

Ziply Fiber (EONI)

United States · AI-generated

isp fiber residential legacy

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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
