Summary

Custer Telephone Cooperative

United States of America · AI-generated

residential rural cooperative telecom

CUSTER-TELEPHONE is operated by Custer Telephone Cooperative, Inc.

What it's used for

  • The address space carries rural subscriber traffic, evidenced by reverse DNS entries pointing to custertel.net (e.g., gen134-195-86-254.custertel.net, 173-224-190-254.custertel.net).
  • The AS announces 5120 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour, a ratio characteristic of a local access network rather than a transit provider.
  • Traffic consists of voice, high-speed internet, and wireless communications for residents and businesses in Central Idaho, specifically the Challis area and the entrance to the Frank Church Wilderness Area.

Notable

  • All registrants for the announced prefixes are listed as Custer Telephone Cooperative, Inc., matching the AS holder.
  • The address inventory is composed of several /22 blocks and smaller /23 and /24 allocations, all registered under the cooperative's name.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
