About this network

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, netname NETBLK-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 /20 is 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.
