About this network

A handle ending in a compass direction, over a netname built from a city the company name never mentions.

What it's used for

• A banking group's shared IT provider. One IPv4 /19 and one IPv6 /37 announced from Germany, eight thousand one hundred and ninety-two addresses, across two observed BGP neighbours.

Notable

• The AS handle is the company name, the two letters for an autonomous system, and a three-letter word meaning east, so the number covers one region of a provider that must have had others.
• The netname is a country code, a three-letter city abbreviation and a date from the year two thousand, and that city is absent from the holder's name.
• One contact is the company's two initials followed by two ordinary words, one capitalised and one not.
• Another is the company name with the registry's own abuse field appended in capitals.
• The holder's legal form is two abbreviations joined by an ampersand, with a full stop inside it.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Regional data-processing centres for savings banks were merged into one national provider over years, and the compass point in the handle is what is left of the arrangement that preceded it. The other directions had their own numbers once.
• Eight thousand addresses behind two neighbours, with nothing answering a reverse lookup, is a network that exists to connect branches to a data centre and to nobody else.
