About this network

A German IT services company in the Münster region, selling connectivity and hosting to business customers.

What it's used for

• Business connectivity and hosted services. 24,320 addresses over six prefixes, one IPv6 /32, one observed BGP neighbour.

Notable

• Every netname reads DE-UNI-X, dated 970808 and 990317 — the company's earlier name, still labelling five of the six blocks.
• Five of the prefixes are consecutive pieces of 195.60.96.0/19: a /20, a /21, a /22, a /23 and a /24, each half the size of the last.
• The registry lists "Abteilung Technik" as a contact — the technical department, as a department rather than a person.
• The AS handle holds a street address, Kiebitzpohl 77, in place of a description.

Interesting

• A descending ladder of prefixes out of one range is what happens when a block is handed out a piece at a time and each piece gets announced as it is used. The shape is a record of growth, and it also means the covering /19 is never announced as such — the parts are visible and the whole is not.
• UNI-X in five netnames and avency on the door is the ordinary fate of a rebrand. Address registrations are updated when something forces the issue, and a name in a netname field forces nothing.
