Summary
LaValle Telephone Cooperative
isp legacy
LTC-1 belongs to LaValle Telephone Cooperative, a member-owned rural telco serving LaValle, Ironton and Cazenovia in western Wisconsin. Founded in 1956, it now runs a fibre network across roughly 877 square miles and seven exchange areas.
What it's used for
Residential and small-business broadband, voice and TV for a scattered rural subscriber base — the classic co-op ILEC profile, funded in part through the federal BEAD programme to reach premises that have no wired service at all.
Notable
The routing picture is unusual and worth stating precisely: RIS observes zero IPv4 prefixes from this AS and exactly one IPv6 prefix, 2602:fa22::/40, through a single neighbour. This is not a broken pack — the counters and the prefix lists agree. The honest reading is that AS11944 currently originates only the co-op's IPv6 block; whatever IPv4 its subscribers use is not being announced from this AS number in the observed window, and the pack gives no evidence about where it lives instead.
Interesting
A single upstream neighbour is a real operational fact about a network this size: rural co-ops frequently reach the internet through one aggregation partner, so redundancy is bought upstream rather than run in-house. It also means the IPv6 /40 is visible globally only for as long as that one relationship holds.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
