About this network

Two blocks carry the same carrier-plus-company netname, and one of them has a letter wrong.

What it's used for

• A regional provider's network. Ten prefixes announced from the United States, one of them IPv6, six thousand six hundred and fifty-six addresses, through seven observed BGP neighbours.

Notable

• Six blocks carry the company's name alone as their netname, with no country code, no date and no numeral to distinguish them.
• Two more pair a carrier's four-letter abbreviation with a four-letter cut of the company name. The two abbreviations of that carrier differ by one letter, so one of the pair is misspelled and both have stayed that way.
• A ninth block is named after a different company with a year appended, and is registered to that company rather than to the holder.
• Twelve of eighteen queried addresses answered. Eleven use the address hyphenated into four parts, the word for a static assignment, and a domain built from the brand plus the word for fibre.
• The twelfth is a city name on the brand's shorter domain, so one router in the sample is named for where it sits rather than for the address it answers on.
• Several answers are block boundaries and resolve like everything else.

Interesting

• A one-letter difference between two otherwise identical netnames is invisible until someone searches for one and finds half the blocks. Nothing in the registry cross-checks them, so the typo is permanent.
• The one hand-named router among a dozen generated names is where the network stops being a spreadsheet and starts being a building.
