Summary

Great Healthworks, Inc

United States of America · AI-generated

business corporate colocation

GREAT-HEALTHWORKS-4150-BUILDING is operated by Great Healthworks, Inc.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames GHW-68-64-95-0-COLO and GHW-HQ-4150-BUILDING, alongside leased blocks from CenturyLink Communications, LLC and Comcast Cable Communications, LLC.
  • The AS announces 1024 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and web/API endpoints for a direct-to-consumer health supplement company, including VoIP media and signalling for internal communications.

Notable

  • Registrants for two of the four announced prefixes are Great Healthworks, Inc, while the remaining two are held by CenturyLink Communications, LLC and Comcast Cable Communications, LLC, reflecting leased space or post-acquisition history.
  • The address inventory is finely subdivided into four /24 blocks, consistent with site-by-site segmentation for a single corporation.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
