Summary

San Juan Regional Medical Center

United States of America · AI-generated

medical business enterprise us

The AS handle SJRMC-ASN is held by San Juan Regional Medical Center Inc.

What it's used for

  • The address space is dedicated to the hospital's internal network, evidenced by netnames SJRMC--162-33-4-0-1 and SAN-JUAN-REGIONAL-MEDICAL-CENTER registered to the same entity.
  • The inventory consists of 512 IPv4 addresses across 2 prefixes, with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access provider.

Notable

  • Both registrants in the RDAP data match the AS holder, confirming direct ownership of the announced prefixes.
  • The address inventory is finely subdivided into two /24 blocks, consistent with site-specific segmentation for a single facility.

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: 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.
