Summary

United States of America · AI-generated

isp rural telecom mobile

MTWEST is operated by Montana West, L.L.C., a regional telecommunications provider in Montana.

What it's used for

  • The address space carries subscriber and enterprise traffic for rural Montana communities, evidenced by netnames such as COMMUNITY-TEL-INC, MONTANAWEST, SKC2, and HOT-SPRINGS-TEL-CO.
  • The AS announces 6,912 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, with only 3 observed routing neighbours, indicating a local access network rather than a transit provider.
  • Traffic consists of residential broadband, business internet, and wireless services for towns like Ronan, Polson, and Hot Springs, as well as institutional connectivity for Salish Kootenai College.

Notable

  • Registrants include Ronan Telephone Company, Montana West, L.L.C., and Salish Kootenai College, reflecting a portfolio of acquired local telephone companies and institutional partners.
  • The inventory is fragmented across multiple /22, /23, and /24 blocks, consistent with the consolidation of smaller regional carriers into a single operational entity.
  • Reverse DNS entries like ppp206-183-122-254.polson.net confirm the use of PPP-based access technologies for end-user connectivity.

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 1,783 prefixes, as published 2026-10-17. 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.
