About this network

A web host whose oldest blocks carry allocation dates from before the web existed.

What it's used for

• A web hosting company's network. Twenty-five IPv4 prefixes and nineteen IPv6 prefixes announced from Germany, thirty-four thousand eight hundred and sixteen addresses, across a hundred observed BGP neighbours.

Notable

• Every netname is a country code, the company name run together without spaces, and a date. Those dates run from the early nineteen-nineties to the end of the twenty-tens.
• The three oldest predate the company's own appearance in the routing archive by twenty years, so those blocks were bought rather than allocated.
• The IPv6 announcements double at every step, running from one small prefix through eight successively shorter ones out of a single allocation.
• The registered holder is a private individual trading under a company name, and one role account serves as both hostmaster and abuse contact.
• The AS handle writes the legal form's conjunction as a word where the holder string uses an ampersand.
• Of eighteen addresses queried, one returned a name: a letter, a five-digit server number, and a domain meaning agency server under a country suffix that is not the one the network announces from.

Interesting

• Sequential server numbers in the tens of thousands are a shared hosting platform counting machines, and the count is published to anyone who asks. It is a rough census of the estate.
• Buying nineteen-nineties address space is the modern way to grow. The dates are the previous owner's.
