AS14957 — PREPA-UUNT1

AS14957 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

The electric utility for an entire island, announcing 256 addresses through one upstream.

What it's used for

• A public power authority's network. 256 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.

Notable

• The whole footprint is 66.129.166.0/24, carrying the netname FROM-PREPANET.
• That netname begins with a preposition, which reads as half of a sentence somebody never finished.
• The AS handle joins the authority's initials to an abbreviated carrier name.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• A netname starting with a word like this one usually comes from a transfer note: space moved from one network to another, and the phrase describing the move became the name. Registry fields keep whatever was typed, including the half-thoughts.
• One upstream and one small block for the utility that powers an island is the fact worth pausing on. The systems that run generation and distribution are not on the public internet, and should not be, but everything that connects this authority to the outside world runs through a single link.
• The carrier name in the AS handle belongs to a company that has been absorbed more than once since the handle was assigned, which dates the record without needing a timestamp.
• Nothing published in reverse DNS is the right answer for an operator of critical infrastructure, and it is consistent across the whole sample.
