AS13547 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

The netname truncates the hospital's name by one letter and then spells out its address in full.

What it's used for

• A hospital's network. 256 addresses in one IPv4 prefix, 64.30.34.0/24, two observed BGP neighbours, and no IPv6 announced.

Notable

• The block is netname LVLT-PORTE-11-64-30-34, registered to the hospital.
• That string carries a carrier's initials, five letters of the customer name, a sequence number and the address with dots replaced by hyphens.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Cutting the name to a fixed five characters is a field-width limit from whatever system generated the record, and it drops the last letter without noticing. The sequence number after it says this was the eleventh such assignment in that batch, so the generator was busy.
• The carrier's initials survive in the netname even though the carrier was absorbed years ago and the registrant was updated to the hospital. Registries correct the ownership line because someone asks; the identifier stays because changing it breaks every reference to it.
• Two upstreams for one small block is the right trade for a hospital. There is very little to reach from outside, but the little there is has to answer at three in the morning.
