About this network

The netname substitutes a different word for the one in the hospital's name.

What it's used for

• A community hospital's network. 256 addresses in the single IPv4 prefix 198.22.136.0/24, three observed BGP neighbours, and no IPv6 announced.

Notable

• The block is netname SHORE-MEDICAL while the registrant reads Shore Memorial Hospital.
• The two words share their first three letters and nothing else.
• The AS handle is SMH, initials taken from the registrant rather than from the netname.
• First seen in the routing archive on 2006-03-28, timestamped in the afternoon rather than the usual morning.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Swapping one word for another that starts the same way is the kind of substitution that happens when a name is entered from memory rather than copied. The netname is not wrong about who holds the block, only about what they are called, and it stays that way because nothing checks.
• Three upstreams for a single /24 is more redundancy than most organisations this size buy. For a hospital, where the network carries records and imaging between sites, the extra path is worth more than the address count suggests.
• A single small block with three paths into it and nothing answering a reverse lookup is a network built to stay up and stay quiet.
