About this network

A rural hospital with its own AS number and a /24 from a range allocated after the address space ran short.

What it's used for

• A community hospital's network. 256 addresses in one IPv4 prefix, 23.129.0.0/24, two observed BGP neighbours, and no IPv6 announced.

Notable

• The block is netname MDMHC, registered to the hospital corporation.
• The AS handle is the same initials without the final letter for the corporate form.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• A netname and a handle differing by one character, both abbreviations of the same name, is what happens when two records are filed by the same person at different times without a written convention. Neither is wrong and neither matches.
• The block sits at the very start of its range, the first /24 in it, which means it was among the earliest assignments made from space released long after the original allocations. A small hospital was near the front of that queue.
• Two upstreams for a single /24 is redundancy bought for availability rather than capacity. A rural hospital's outside connections are records exchange, imaging transfer and telemedicine to larger centres, all of which matter most when the weather is bad.
