Summary

Grande Communications Networks

United States of America · AI-generated

residential isp cable us

NET3-ISP is held by Ridgewood Holdings LLC, the corporate parent of Grande Communications Networks.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as 24-155-43-64.dyn.grandenetworks.net and netnames like GRANDECOM-03 and GRANDECOM-05.
  • With 1792 IPv4 addresses announced across 5 prefixes and only 1 observed neighbour, the network functions as an access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for cable internet services in the New York City area, specifically within the Ridgewood and Maspeth enclaves.

Notable

  • Registrants for the majority of prefixes are Grande Communications Networks, LLC, while the largest block 38.108.6.0/23 is registered to The Fusion Network, LLC under the netname RTA-CGNT-NET-1.
  • The address inventory is a mix of legacy and acquired space, with the 24.155.x.x and 65.36.x.x blocks clearly branded as Grande Communications, while the 38.108.x.x block retains a different registrant identity.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
