Summary

Reach Broadband

United States of America · AI-generated

cable residential access isp

The AS handle REACHBROADBAND is held by Reach Broadband LLC.

What it's used for

  • The address space carries cable modem termination system (CMTS) and customer premises equipment, evidenced by netnames like RB3-CABLE and reverse DNS entries pointing to rpmcable.com (e.g., odessa-107-178-22-128.rpmcable.com).
  • The network announces 2816 IPv4 addresses across 6 prefixes and maintains a single observed neighbour, a ratio characteristic of a local access or eyeball network rather than a transit provider.

Notable

  • All registrants in the RDAP data align with the announcer, consistently listing Reach Broadband LLC for every prefix in the inventory.
  • The address inventory is concentrated in the 107.178.0.0/16 range, specifically within the 107.178.16.0/22 block and several adjacent /23 and /24 prefixes, indicating a contiguous 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: 448 networks and 1,851 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.
