About this network

The AS handle is a street, a house number, a postcode and a town.

What it's used for

• A communications company's network. Twenty-seven IPv4 prefixes announced from Germany, no IPv6, sixteen thousand eight hundred and ninety-six addresses, across one hundred and seven observed BGP neighbours.

Notable

• The handle carries the brand and then a full postal address, including a country letter joined to the postcode by a hyphen.
• Most blocks share one netname of a country code, the brand and the date 20041119, so a large batch was registered on a single day.
• One older block carries a date four years earlier, and two carry only the brand with the three letters for a network, with an abuse role as their sole registrant.
• The company writes its own brand in lower case in the registrant field and in capitals everywhere else.
• Twenty-seven announcements cover two ranges, split down to /24s in places while the surrounding space is announced whole.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• One hundred and seven neighbours against sixteen thousand addresses is the ratio of a network that peers rather than buys. The addresses are almost incidental; what this number is for is being present at exchanges.
• A postal address in a handle dates from when the registry doubled as a phone book, and it has outlived every system that would have used it.
