AS15562 — SNIJDERS

AS15562 announces 8 IPv4 prefixes covering 2,368 addresses and 6 IPv6 prefixes.

About this network

One of the announcements is a /26, far smaller than the global routing table normally carries.

What it's used for

• A network held by an individual rather than a company. Ten IPv4 prefixes and six IPv6 prefixes announced from the Netherlands, three thousand addresses, across nine observed BGP neighbours.

Notable

• One IPv4 announcement is a /26, four times smaller than the smallest size most networks will accept from a peer, so it can only be useful where a specific arrangement carries it.
• Not one of the ten IPv4 blocks is registered to the holder. Six belong to one global carrier, one to a hardware and software vendor, one to that carrier's national arm, and one to two named individuals.
• The six IPv6 prefixes come from six unrelated ranges, including one the registry uses for measurement infrastructure.
• Blocks span address space administered by two different regional registries while being announced from one country.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A network assembled entirely from other people's address space is what an operator running experiments looks like. The blocks are borrowed, the announcements are the point.
• Announcing a /26 is not an error so much as a demonstration. It shows exactly which paths carry prefixes that long, which is information you cannot get any other way.
• Six IPv6 prefixes and ten IPv4 ones on three thousand addresses is heavily weighted toward the newer protocol, which is the opposite of almost everything else in this range.
