Summary

Baptist Health System

United States of America · AI-generated

healthcare business enterprise

BAPTISTHEALTH is the autonomous system for Baptist Health System.

What it's used for

  • The space carries internal corporate infrastructure, evidenced by the reverse DNS record exchange2010.bmcjax.com and the netname BAPTISTHS1.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The registrant Baptist Health System matches the AS handle and netname, confirming consistent ownership.
  • Baptist Health System is a hospital and medical facility system located in San Antonio, Texas, and is owned by Tenet Healthcare.
  • The address inventory consists of a single /24 block, 192.251.111.0/24, which is finely subdivided 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: 454 networks and 1,854 prefixes, as published 2026-11-09. 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.
