Summary
TCT West (TCT)
isp legacy
TCT-AS is the network of TCT West, Inc. — a broadband, telephone, and TV provider serving the Big Horn Basin of northwestern Wyoming and parts of southern Montana, with its corporate office in Cody, Wyoming.
What it's used for
- Residential and small-business internet across towns including Basin, Cody, Greybull, Lovell, Powell, and Meeteetse, delivered over fiber, copper, and fixed wireless.
- VoIP telephone, television, and business IT services for the same rural footprint.
Notable
- Classic rural-telco eyeball space: TCT West grew out of Tri County Telephone and serves exchanges that larger carriers never reached.
- The address space is a patchwork of small blocks accumulated over decades of serving a sparsely populated region.
Interesting
- Companies like TCT are why parts of rural Wyoming have fiber to the home while denser suburbs elsewhere still run on aging copper — the local co-op or independent telco built it because nobody else would.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
