AS13930 — CMH

AS13930 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

A three-letter handle, a single block, and a netname that promised a second one.

What it's used for

• A children's hospital's network. 256 addresses in a single IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

• The block is 199.242.168.0/24, netname CMH-BLK-1, registered to The Children's Mercy Hospital.
• The AS handle is the same three letters.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Three-letter handles were first come, first served, and the ones worth having went early. Those initials belong to a great many organisations and an airport besides, so anyone searching the registry by them finds this hospital only by knowing the number already.
• The -1 on the netname is a counter that stopped at one. Every registry is full of them: the field is filled in expecting growth, the growth goes elsewhere, and the suffix is left describing a series with one member.
• A /24 behind one upstream is the smallest a network gets while still holding its own space. For an institution whose systems are reached from inside the building, the addresses matter more for what they let in than for what they publish.
