AS15594 — NETZQUADRAT netzquadrat GmbH

AS15594 announces 4 IPv4 prefixes covering 24,576 addresses and 3 IPv6 prefixes.

About this network

Ninety-six neighbours on four blocks, and the AS handle ends in a house number.

What it's used for

• A provider's network. Four IPv4 prefixes and three IPv6 prefixes announced from Germany, twenty-four thousand addresses, across ninety-six observed BGP neighbours.

Notable

• The AS handle runs the company name straight into a street name and a house number, so the field that should identify the network gives a postal address instead.
• All four blocks follow one netname scheme: country code, a two-letter company abbreviation and the allocation date, with dates spread across eight years.
• The IPv4 holding is two /19 blocks and two /20 blocks, an unusually regular shape for space collected over that long.
• The three IPv6 prefixes are one /34 and two /36 pieces carved out of it at widely separated offsets.
• Twelve addresses were queried for reverse DNS and none returned a name.

Interesting

• Ninety-six neighbours is a peering-heavy network, far more connections than twenty-four thousand addresses would need for their own traffic. The value is in what passes through.
• A consistent netname scheme across four allocations and eight years means one person's convention outlived several rounds of paperwork, which is rarer in this data than it should be.
• Announcing two more specific pieces of an IPv6 block alongside the block itself is traffic engineering, and it is still uncommon enough on that protocol to be worth noting.
