About this network

Two blocks, two neighbours, and a netname from the era when a state agency built its own communications network and named it after what it carried.

What it's used for

• A state health department's network. 65,792 addresses across two IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• 150.142.0.0/16 carries the netname HEALTHCOM, registered to New York State Health Department.
• 192.135.176.0/24 carries HEALTHCOM-B, same registrant.
• The AS handle is NYSDOH.
• Six addresses were queried for reverse DNS and none returned a name.
• The routing archive first saw this AS in 2001.

Interesting

• HEALTHCOM names a service rather than an organisation. Agencies that built networks in the eighties and nineties named them for the thing they carried, and the name outlives the technology by decades. The second block simply got a letter appended when the first ran out of room.
• The handle and the registrant disagree about word order. One is the department of health, the other the health department. Both are the same body, filed by different people at different times.
• A sixteen-bit block for a health department is an early allocation, not a measure of size. Public hospitals, laboratories and county offices all hang off it.
• Nothing answers a reverse lookup. A network carrying clinical and reportable-disease traffic has no reason to describe any address to a stranger.
