About this network

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.nl hosting 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.
