About this network

A project code name in a registry field, and one family of routes announced with holes in it.

What it's used for

• A backup and disaster recovery vendor's network. Twenty-five IPv4 prefixes announced from the United States, no IPv6, twelve thousand addresses, across five observed BGP neighbours.

Notable

• One netname is the company name followed by a project label reading as a new build, which is an internal programme name preserved in a public record.
• Another is a carrier's four letter prefix, the customer name and the address written with dashes; a third is only the address with dashes and no name at all.
• Eight of the routes sit inside one large range but skip blocks between them, so the gaps belong to somebody else and the space was handed out piecemeal.
• The two answering addresses are numbered servers, four digits each, under a domain naming the backup product rather than the company.
• Eighteen addresses were queried for reverse DNS and two returned a name.

Interesting

• Sequential server numbers in the thousands are a fleet inventory published by accident. They say how many machines the naming scheme expects, which is more than most operators would choose to disclose.
• Backup vendors hold copies of their customers' data, so this network is a concentration of other people's information. Five upstreams for that job is a reasonable answer.
• Three different naming conventions across twenty-five blocks is the signature of address space acquired over years from several sources, not designed at once.
