AS16089 — IPUBLICATIONS

AS16089 announces 3 IPv4 prefixes covering 768 addresses and 1 IPv6 prefixes.

About this network

Three small blocks collected sixteen years apart, and one IPv6 allocation that dwarfs all of them.

What it's used for

• A publishing software company's network. Three IPv4 prefixes and one IPv6 block announced from the Netherlands, seven hundred and sixty-eight addresses, through a single observed BGP neighbour.

Notable

• All three netnames follow one template: country code, brand, date. The dates run from the late two thousands to the middle of the following decade and then to the current one, roughly one block every six years.
• Each IPv4 block is the same size, so the company has taken the smallest routable allocation three times rather than asking for a larger one.
• The IPv6 allocation holds more addresses than every IPv4 block here multiplied together, which is the ordinary shape of a modern allocation rather than anything unusual about this network.
• Every block lists the same holder and a role contact for abuse, with no individual named anywhere.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• A single upstream and a single brand across three registrations is a company that has never needed to route around anything. The address space grew when the business did, in the smallest increments the registry sells.
• Software companies that publish on behalf of clients end up running networks because their customers' content has to be served from somewhere, and the addresses outlive the products they were bought for.
