Netherlands · AI-generated

isp residential eyeball fiber cable

DELTA Fiber Nederland (DELTA Fiber Nederland B.V.) — a Dutch fixed-broadband provider offering fibre and cable home internet, marketed under the DELTA and Caiway brands.

What it's used for

  • Residential FTTH fibre and coax cable home internet across parts of the Netherlands, especially Zeeland and various regional networks.

Notable

  • An "eyeball" network with a pronounced day/night usage rhythm: addresses here are Dutch home connections, not servers. A challenger to KPN and VodafoneZiggo on the consumer fixed-broadband market.

Interesting

  • Formed by combining regional cable/fibre operators (including Caiway and the legacy Kabelfoon/Zeelandnet networks) under the DELTA Fiber banner.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
