About this network

The autonomous system's own number appears twice in its own record, once with a hyphen after it.

What it's used for

• An IT services company's network. Two IPv4 prefixes announced from Denmark, no IPv6, sixty-nine thousand addresses, through a single observed BGP neighbour.

Notable

• Both the holder string and the AS handle begin with the letters AS and this number, before the company name. The handle separates them with a spaced hyphen.
• The two blocks are a /16 and a /20, and the larger one accounts for almost all of the addresses.
• Their netnames use two different conventions: the bare company name on one, a country code with the company and an allocation date on the other.
• Both list a department rather than a person as the first contact, with an abuse role behind it.
• One upstream carries all sixty-nine thousand addresses.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Putting the AS number inside the AS name is redundant everywhere the number is already shown, which is everywhere the name appears. It turns up often enough in this range to look like a habit of one era's registration forms rather than one operator's choice.
• A whole /16 behind a single neighbour is an old allocation that never needed a second path. The addresses are worth a great deal now and the routing is as simple as it was when they were free.
