About this network

Every reverse name pairs a service class with a three-letter counter that advances through the address space.

What it's used for

• A web hosting and domain company. Forty-four IPv4 prefixes and seventeen IPv6 prefixes announced from Poland, one hundred and two thousand one hundred and forty-four addresses, across one hundred and thirty observed BGP neighbours.

Notable

• All eighteen queried addresses answered, which is rare at this size.
• Each name is a word for the service tier, a hyphen, three lower-case letters, then the last octet, then a label for the reverse zone and a domain.
• Those three letters advance like an odometer as the addresses climb, so they encode the block's position rather than describing anything.
• Three names use a second brand's domain while keeping the identical format.
• The netnames split between a country code with a brand and a date, and names stating the product outright: one for virtual servers, one for shared web hosting.
• The IPv6 prefixes are nested pieces of one range, from a /39 down to a /47.

Interesting

• Encoding position in letters rather than digits keeps names short and fixed width across a hundred thousand addresses, where the address itself would need up to fifteen characters. The tier word in front means an abuse report tells you what kind of customer it is before you look anything up.
• Naming blocks after products rather than dates is what a hosting company does when its address space is inventory, sorted by what is sold from it.
