Summary

Cascade Access

United States of America · AI-generated

residential isp cable dsl

CASCADE-ACCESS-LLC-CA-ESTOR1 is operated by Cascade Access, LLC.

What it's used for

  • The address space carries residential broadband access, evidenced by reverse DNS entries such as pppoe-72-19-37-254.rioaccess.com and ftth-static-72-19-61-254.rioaccess.com.
  • With 13056 IPv4 addresses announced across 13 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates a regional access network rather than a transit provider.

Notable

  • Registrants are predominantly Cascade Access, LLC, though several prefixes (38.19.186.0/23, 38.74.68.0/23, 38.246.120.0/23) list Cogent Communications, LLC as the registrant with netname COGENT-A, suggesting leased or inherited space.
  • The operator is also known as Reliance Connects, a regional cable and DSL ISP.
  • The inventory consists of a mix of /21, /22, /23, and /24 blocks, with no IPv6 prefixes announced.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
