About this network

Eighty-four neighbours, and the reverse names give away who the customers are.

What it's used for

• A hosting and colocation provider. Eleven IPv4 prefixes and one IPv6 /32 announced from the United Kingdom, nearly eight thousand addresses, across eighty-four observed BGP neighbours.

Notable

• One answering address returns an insurance firm's own domain, so a customer is identifiable from the address alone.
• Another names a router interface by port number, router number and site, which publishes part of the internal topology.
• A third belongs to a monitoring host on a fourth unrelated domain.
• One block's netname is simply its own prefix written with dashes, and its registrant is an unnamed private customer under a different hosting brand.
• Another block's abuse role is written in lower case as a single word that reads as an ordinary verb.
• Eighteen addresses were queried for reverse DNS and three returned a name.

Interesting

• Three answering addresses across three unrelated domains is what a hosting network looks like from outside: the addresses are the provider's, the names belong to whoever rents them.
• Eighty-four neighbours for eight thousand addresses is exceptional density. Hosting businesses buy reachability, and this one has bought a great deal of it.
• Netnames spanning many years and two corporate forms, one of them incorporated abroad, trace a company that kept acquiring space and eventually opened a second entity to hold it.
