Summary
Anne Arundel Medical Center
hospital business healthcare internal
The AS handle ANNEARUNDELMEDICALCENTER is held by Anne Arundel Medical Center.
What it's used for
- The address space carries internal hospital infrastructure, evidenced by reverse DNS entries pointing to
aahs.org(e.g.,67-132-207-64.dia.static.aahs.org) and a netname referencingDOCTORS COMMUNITY HOSPITAL. - The AS announces 768 IPv4 addresses across 3 prefixes with only 3 observed neighbours, a ratio consistent with a small, self-contained corporate or institutional network rather than a transit or access provider.
Notable
- Registrants for the announced prefixes include
DOCTORS COMMUNITY HOSPITAL,Comcast Cable Communications, LLC, andCenturyLink Communications, LLC, indicating the space includes both hospital-owned and leased or legacy ISP blocks. - Secondary sources confirm the operator is a nonprofit regional hospital in Annapolis, Maryland, now operating under the Luminis Health system.
- The inventory consists of three /24 blocks, one of which retains a CenturyLink legacy netname, suggesting historical acquisition or lease of address space.

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 1,779 prefixes, as published 2026-10-22. 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.
