Summary

Trinity Health Corporation

United States of America · AI-generated

healthcare business enterprise internal

The AS handle TRINITY-HEALTH is held by Trinity Health Corporation.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the reverse DNS record HNATINTEG.trinity-health.org and the netname TRINITYHEALTH-PUB.
  • The inventory consists of a single IPv4 prefix, 170.232.224.0/20, totaling 4096 addresses, with 0 IPv6 prefixes announced.
  • With only 2 observed neighbours, the low neighbour count relative to the address block indicates a private, internal corporate estate rather than a public transit or access network.

Notable

  • The RDAP registrant Trinity Health Corporation matches the AS holder name exactly, confirming consistent ownership.
  • The address inventory is a single contiguous /20 block, typical of a corporate network segment allocated for internal use.

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 1,773 prefixes, as published 2026-10-13. 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.
