Summary

West River Telecommunications Cooperative

United States of America · AI-generated

cable dsl isp cooperative

The AS handle WRT-AS is held by West River Telecommunications Cooperative.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to westriv.com across all three announced IPv4 blocks.
  • The network announces 16,384 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, maintaining only 3 observed neighbours. This high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • All RDAP registrants for the announced prefixes are consistent with the announcer, listing West River Telecommunications Cooperative for netnames WEST-RIVER and WRVR.
  • The inventory consists of three distinct IPv4 blocks: a /19, and two /20s, alongside a single /32 IPv6 prefix.

Reputation

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
