Summary
i3 Broadband
isp fiber residential legacy
i3 Broadband is a fiber-to-the-home provider serving central Illinois and the St. Louis metro area, previously trading as iTV-3.
What it's used for
- Residential and small-business fiber internet, TV and phone across a set of mid-sized Midwestern cities.
Notable
- The reverse DNS names the town outright. Sampled addresses answer as
fiber-255.Peoria.IL.i3broadband.com,fiber-0.Galesburg.IL.i3broadband.com,fiber-255.Rockford.IL.i3broadband.comandfiber-0.SaintCharles.MO.i3broadband.com, so the footprint is legible straight from the hostnames rather than having to be inferred from the prefixes. - 144,000 addresses across 58 prefixes against only 5 observed BGP neighbours. That is the classic access-network shape: a lot of subscriber space reached through a handful of upstreams, with no interest in being a transit provider.
Interesting
- Nearly every announced block is registered under the single netname
IL-494, which is unusually consistent for a network assembled city by city. i3 builds its own fiber into markets an incumbent already serves, so the plant grows one town at a time while the addressing stays under one roof.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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 1,778 prefixes, as published 2026-10-20. 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.
