AS15234 announces 4 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.

About this network

Two blocks share a netname that is a provider's name and a single letter.

What it's used for

• An energy trading software company's network. Four IPv4 prefixes announced from the United States, no IPv6, and four observed BGP neighbours.

Notable

• Two of the four blocks are registered to a transit provider under one netname: the provider's name followed by a single letter, with nothing to distinguish the two assignments from each other.
• One block is registered to the company itself, with a netname that appends the block's address to the company name and a registrant that adds an operations centre after a semicolon.
• One block's registry lookup failed, so nothing can be said about who holds it.
• Twelve addresses were queried for reverse DNS and none returned a name.
• Two thousand addresses across four announcements and four upstreams.

Interesting

• A netname of a provider's name plus one letter is the least specific label that still parses. It says which provider and nothing else, and it appears on blocks in different ranges, so it cannot be used to tell assignments apart.
• Half the space here belongs to the provider and half to the company, which is what a network looks like partway through moving to its own address space. The provider's blocks go back when the contract does.
• Four upstreams for two thousand addresses is a company that treats connectivity as the product's dependency rather than an office utility, which fits software that sits between energy markets.
