United States of America · AI-generated

fiber residential isp business

GREENLIGHT-NETWORKS is operated by Greenlight Networks, LLC.

What it's used for

  • The address space carries fiber internet services for residential and small business customers, evidenced by netnames such as GREENLIGHT-CGNT-NET-1 and GNL-22.
  • The AS announces 42,240 IPv4 addresses across 33 prefixes and 137 IPv6 prefixes, while maintaining only 3 observed neighbours, a ratio indicative of an access network rather than a transit provider.

Notable

  • Registrants for the largest prefixes are primarily Greenlight Networks, LLC, though two /20 blocks (23.226.80.0/20 and 209.94.32.0/20) are registered to Plexicomm, LLC under netnames PLEXICOMM and PL-7.
  • Greenlight Networks is an acquired company that joined a 50/50 joint venture with T-Mobile and Oak Hill Capital, alongside GoNetspeed, to expand fiber infrastructure across the Northeast.
  • The inventory includes a mix of /20, /21, /22, and /23 IPv4 prefixes, with the largest blocks being 8.9.80.0/20, 23.226.80.0/20, and 209.94.32.0/20.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
