Summary
Cubic Circle B.V. (CuCi)
hosting legacy
CUCI is Cubic Circle B.V., a long-established Dutch internet company based in
Simpelveld in the south of the Netherlands, known by its cuci.nl domain.
What it's used for
- Hosting, virtual servers, domains and mail for Dutch customers, plus the connectivity underneath them.
- A modest set of prefixes, announced through a small number of upstreams.
Notable
- Server-side address space: reverse DNS across the range is dominated by
*.cuci.nlhosting hosts rather than access lines, so traffic from it looks like hosted services rather than end users. - A small, independent provider holding an AS number in a range otherwise full of national carriers — a survivor of the mid-1990s wave of Dutch ISPs, many of whose peers were long ago absorbed into larger groups.
