About this network

Twenty-seven prefixes, four netname schemes, and every one of them answers on the same reverse domain.

What it's used for

• A rural telephone cooperative's network. Twenty-eight prefixes announced from the United States, one of them IPv6, fifty-seven thousand and eighty-eight addresses, through four observed BGP neighbours.

Notable

• The largest block's netname is the word for a network followed by its own address and the prefix length, all hyphenated. It describes the block's coordinates and names nobody.
• Two blocks spell the cooperative out in four hyphenated words with the letters for a provider on the end. Nine more use four initials and a numeral nine, unchanged across every one of them.
• Extra contacts differ block by block: two list a job title, one lists what reads as a login name rather than a person or a team.
• Fifteen of eighteen queried addresses answered, every single one with its own address hyphenated into four parts and then the same four labels: a word for a shared pool, an access technology, and the cooperative's domain.
• Those answers span blocks from many separate parent ranges, so address space collected from all over is presented under one name.

Interesting

• A cooperative that has gathered twenty-seven prefixes has been buying address space wherever it came available, and the registry shows the seams. Reverse DNS shows none of them, because that is the part subscribers see.
• Naming every subscriber address after an access technology is a snapshot of what the network sold when the zone was written. The label outlives the equipment.
