AS13972 WADSWORTH-CENTER
Unclassified ARIN
Summary
Wadsworth Center
research government
The registry still calls it a plural, which the holder no longer does.
What it's used for
- A public health laboratory's network. 4,096 addresses in a single IPv4 prefix, four observed BGP neighbours, and no IPv6 announced.
Notable
- The block is
199.184.16.0/20, netnameNETBLK-WADSWORTH. - The registrant is
Wadsworth Centers for Laboratories and Research. - The AS holder is
Wadsworth Center, NYS Department of Health. - Routing was first seen in 2000.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- The registrant is the older name and the holder is the current one. A
NETBLK-prefix on the netname dates the assignment too: that convention belongs to an era of the registry that has long since stopped being used for new records, and nothing rewrites the old ones. - A
/20is a large single block for one laboratory, and it arrived as one contiguous piece rather than as accumulated fragments. Institutions that requested space early got it in sizes that would not be granted today, and they kept it. - A state health department running its own AS number rather than sitting behind the state network is a decision about independence. It means the laboratory chooses its own upstreams and its routing survives changes to whatever the parent agency does.

Internet exchanges
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 2026-10-24, 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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
