AS15096 announces 3 IPv4 prefixes covering 768 addresses and 2 IPv6 prefixes.

About this network

Three blocks, three different holders, and none of them the network that announces them.

What it's used for

• A small network held by a private party rather than a company. Three IPv4 /24 blocks and two IPv6 /48 prefixes announced from the United States, with a single observed BGP neighbour.

Notable

• No announced block is registered to the holder. One belongs to a company whose corporate form is GmbH, under the netname DNXNET, one sits under PEGASUS-NET registered to a separate private party, and the third lookup failed.
• The blocks are announced from the United States while the registry entries and the reverse names point somewhere else entirely, so the routing and the paperwork disagree.
• Three of nine sampled addresses answered, all in the form host-64.he.dnx.de, which matches the DNXNET netname's domain and carries a two-letter label that appears nowhere else in the record.
• The two IPv6 prefixes come from allocations with nothing in common, so they were obtained separately.

Interesting

• This is what a network assembled from borrowed space looks like. Every block traces to someone else, the reverse names belong to one of those someones, and the only field tying the pieces together is the AS number itself.
• Announcing from one region what is registered in another is legitimate and routinely misread. Geolocation built from registry data will place these addresses far from where they are announced, and the reverse names will agree with the registry rather than with the routing.
