Summary

3 Rivers Telephone Cooperative

United States of America · AI-generated

telecom cooperative rural residential

The AS handle 3RC is operated by 3 Rivers Telephone Cooperative, Inc.

What it's used for

  • The address space carries residential and business connectivity for a rural telephone cooperative, evidenced by reverse DNS entries pointing to 3rivers.net and netnames such as 3-R-SERVICE-EXPANSION and 3-RIVERS-REALLOCATION.
  • The AS announces 23,296 IPv4 addresses across 29 prefixes while maintaining only 4 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

  • All registrants in the RDAP sample are consistent with the announcer, listing 3 Rivers Telephone Cooperative, Inc. for every prefix.
  • The inventory consists of a mix of /21, /22, /23, and /24 blocks, with the largest being 192.230.160.0/20, reflecting a fragmented but cohesive corporate estate.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
