Summary

Team Health

United States of America · AI-generated

business healthcare corporate

The AS handle TEAM-HEALTH is held by Team Health, Inc.

What it's used for

  • The address space carries corporate infrastructure for a healthcare staffing firm, evidenced by netnames TEAMHEALTH and registrants Team Health, Inc. and TEAM HEALTH - TYS.
  • With 1536 IPv4 addresses across 3 prefixes and only 2 observed neighbours, the ratio indicates an internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, including Team Health, Inc. for the largest block and TEAM HEALTH - TYS for a smaller prefix.
  • The inventory consists of three distinct IPv4 prefixes with no IPv6 announcements, reflecting a segmented internal network structure.

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 1,779 prefixes, as published 2026-10-21. 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.
