About this network

Forty-seven neighbours for a single /24, and a reverse name that says what the server runs.

What it's used for

• A digital agency's network. A single IPv4 /24 and one IPv6 /48 announced from Switzerland, across forty-seven observed BGP neighbours.

Notable

• Forty-seven neighbours against two hundred and fifty-six addresses is one of the highest ratios of interconnection to address space you will see.
• Three identifiers, three different names: the AS handle, the netname and the holder share no words at all.
• The netname begins with a stray letter before what reads as a product name, then the word services.
• The one answering address names an open source web analytics package on the company's own domain.
• Three addresses were queried for reverse DNS and one returned a name.

Interesting

• That neighbour count is the point. This is a network built to peer at exchanges rather than to hold addresses, and it buys reachability that a much larger network might not have.
• Naming the analytics platform in reverse DNS discloses what software is running before anyone connects. It is also a quiet statement, since self-hosting analytics is a choice about not sending visitor data elsewhere.
• Three unrelated names across three fields makes this network hard to attribute from any single lookup, which is worth remembering when a tool shows you only one of them.
