About this network

The AS handle contains a street address.

What it's used for

• A hospital's network. 512 addresses across two IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• The AS handle is FMC-401NEWING-LOH: the hospital's initials, a building number, a street name cut short, and a location code.
• 199.103.118.0/24 carries the netname FAIRFIELDMEDICALCENTER, twenty-two characters with no separators at all.
• 98.100.80.0/24 carries the generated netname NET-98-100-80-0-1.
• Three addresses answer as syn-098-100-080-064.biz.spectrum.com, with each part of the address padded to three digits.

Interesting

• Putting a postal address in an AS handle is the most literal identification in this range. It was written by somebody thinking about which building the circuit terminates in, which is the right question for a hospital with more than one site and the wrong field to answer it in.
• The two netnames are opposite failures. One runs the whole name together with nothing to separate the words; the other has no name at all, only the addresses restated. Neither was written by someone expecting a person to read it.
• Zero-padding every part of the address in a hostname makes the names sort correctly as text, which is why carriers do it. It also makes the address slightly harder to recognise at a glance.
• Those padded names belong to a carrier's business service, so this block follows the contract rather than the hospital, and the reverse zone is not the hospital's to change.
