Summary

Baptist Memorial Health Care

United States · AI-generated

research business infrastructure

Ten prefixes that cover the whole range except for one /23-sized hole in the middle of it.

What it's used for

  • A hospital system's network. 65,024 addresses across ten IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Notable

  • Every record checked carries the netname BMHCC, registered to Baptist Memorial Health Care Corporation, with a networking group as contact.
  • All ten prefixes sit inside 167.251, from a /17 down to a /23.
  • The announced total is one /23 short of a full sixteen-bit range, and the gap sits between 167.251.32.0/20 and 167.251.50.0/23.
  • Eighteen addresses were queried for reverse DNS and none returned a name.
  • The registry lookup for 167.251.50.0/23 failed.

Interesting

  • The missing piece is the interesting part. Everything either side of the gap is announced, so the hole is not the edge of an allocation: it is a piece of the range that has been carved out, and whatever holds it is not this network. Address space gets lent, sold or simply forgotten in units this small.
  • The contact is a department rather than a person, which is what a hospital's registry entry should look like. Staff turn over; the networking group does not.
  • Three neighbours across a system spanning several hospitals. Clinical networks buy redundancy at the circuit level rather than by collecting adjacencies.
  • Nothing answers a reverse lookup on any address sampled.

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 2026-11-06. 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.
