Unclassified APNIC
Summary
Fox Valley Internet
isp legacy
FVI-CHI is Fox Valley Internet, a small regional ISP based in Elgin, Illinois, serving rural and exurban communities in the Fox Valley area west of Chicago. RIS observes 31 announced IPv4 prefixes covering about 7,936 addresses, no IPv6, and a single BGP neighbour.
What it's used for
This is an eyeball access network. Every announced prefix is a /24 carved out of 64.135.192.0/18, and sampled reverse DNS returns first-party generic per-address names in the shape 64-135-223-5.FoxValley.Net. That naming pattern — the IP itself templated into the hostname under the operator's own domain — is the standard way an ISP labels subscriber and pool addresses at scale, and it confirms Fox Valley both holds and operates the space rather than reselling it to a third party. The company delivers service over fixed wireless and cable to homes and small businesses across dozens of northern Illinois towns, and also sells VoIP, hosted email, and security services.
Notable
The announcement pattern is striking: 31 separate /24s and no covering aggregate. Deaggregating a /18 into its component /24s is usually a sign of address space allocated and lit up piecemeal over many years, and it is a common habit at long-lived small ISPs. With just one observed neighbour, this AS is a single-homed stub — no transit role, no peering fabric, just a network reaching its upstream.
Interesting
Fox Valley has been in business since 1996, which fits both the low ASN and its legacy 64.135.x space.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
