AS11944 — LTC-1 - LaValle Telephone Cooperative

AS11944 announces 0 IPv4 prefixes covering 0 addresses and 1 IPv6 prefixes.

About this network

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.
