About this network

The reverse names repeat the same city label twice in a row, and nothing in the record explains why.

What it's used for

• A wireless provider's network. Six prefixes announced from the United States, two of them IPv6, two thousand five hundred and sixty addresses, through two observed BGP neighbours.

Notable

• The AS handle stacks two brands and a numeral: one company's name run together, then the provider's own name, then a two-digit count.
• Two blocks are registered to the provider. One netname abbreviates the first brand to a single letter and ends in a numeral written without a separator; the other is just the provider's name.
• The other two blocks are registered to a cable company instead, under netnames that begin with the word for a network block and then encode a city and the address. The city is written three letters in one and two in the other, and the carrier's own abbreviation gains a letter between them.
• Two of twelve queried addresses answered, both with four letters for a subscriber address, the address hyphenated, and then the same city label written twice before the cable company's domain.

Interesting

• A small wireless provider announcing a larger carrier's address space is the ordinary shape of the last mile: the radios are the provider's, the addresses are rented, and the registry follows the money rather than the antennas.
• A doubled label in a reverse zone is a template that took a location twice and was given the same answer both times. It costs nothing and never gets fixed.
