AS13572 LAHEYCLINIC - Lahey Clinic, Inc.
Unclassified ARIN
Summary
Lahey Clinic
business enterprise infrastructure
Two /21s, one netname, one upstream, and a registrant that names the team that filed it.
What it's used for
- A hospital group's network. 4,096 addresses across two IPv4 prefixes,
199.255.48.0/21and208.64.112.0/21, one observed BGP neighbour, and no IPv6 announced.
Notable
- Both blocks are netname
LAHEYCLINIC, registrantLahey Clinic, Inc.; Network Services. - The AS handle is the same string as the netname.
- Six addresses were queried for reverse DNS and none returned a name.
Interesting
- The semicolon and the department after it is a registry convention for recording which internal team owns the record. It is a small disclosure, and a consistent one: both objects carry it, so the same group filed both.
- Two /21s from unrelated ranges, announced whole with no subdivision, is a network that grew by being given a second allocation rather than by splitting the first. Nothing here is being steered; the routing table sees exactly what the registry sees.
- One upstream for a hospital group is the number that stands out. Clinical systems mostly face inward, and the connections that matter to a hospital are private circuits to labs, insurers and affiliated practices, none of which appear in a routing table.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
