ASEM-PRandASEMDEPRregistered to the Puerto Rico Medical Services Administration. - The AS announces 1792 IPv4 addresses across 3 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or large-scale access provider.
Notable
- All registrants for the announced prefixes (
200.5.4.0/22,200.5.2.0/23,204.27.224.0/24) consistently identify the Puerto Rico Medical Services Administration, matching the AS holder. - The inventory consists of three distinct IPv4 blocks with no IPv6 prefixes, reflecting a legacy or segmented internal estate for a specific government agency.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
