Summary

River Canyon Wireless

United States of America · AI-generated

wireless isp rural fixed

The AS handle RCW is held by River Canyon Wireless.

What it's used for

  • The address space carries fixed wireless internet service, with all four announced prefixes registered under the netname RCW and registrant River Canyon Wireless.
  • The network announces 5120 IPv4 addresses across 4 prefixes and maintains a single observed neighbour, a ratio characteristic of an access network serving local subscribers rather than a transit provider.
  • Traffic from this AS consists of residential and small business fixed wireless connections in rural areas of Utah and California, where the operator provides broadband internet access.

Notable

  • All registrants in the RDAP data agree with the announcer, consistently listing River Canyon Wireless as the holder for every announced prefix.
  • The address inventory is composed of two /21 blocks and two /23 blocks, all located in the United States, with no IPv6 prefixes in inventory.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
