About this network

Brand, city code and country code, and the same three-part string does duty as every label in the record.

What it's used for

• A company's own network. A single IPv4 prefix announced from Poland, no IPv6, two hundred and fifty-six addresses, through two observed BGP neighbours.

Notable

• The netname is three parts: the company brand, three letters for the city it operates from, and a two-letter country code. It reads like an airport board and identifies the block precisely.
• The AS handle is built from the same parts, and the holder field opens with the same string before giving the company's legal form, so one label is reused in three places.
• The block is registered to the company and to an abuse role whose label spells out that it handles abuse, in words rather than the usual abbreviation.
• The routing record begins nearly a decade after the number's range was issued, so the number waited before it was used.
• Two upstreams on a single smallest-routable block is redundancy on the smallest possible network.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• A three-letter city code inside a netname is doing work no other field does. The registry records a country and a company; the city is the operator's own note about where the equipment actually is.
• Consistency across every field is rarer in this range than any of the collisions, and it means one person wrote all three at the same time from the same template.
