Summary
Fundaments
hosting business netherlands
FUNDAMENTS-AS is operated by Fundaments B.V., a Dutch hosting and cloud services provider.
What it's used for
- The address space carries hosting and cloud infrastructure, evidenced by the reverse DNS record
node-5.parantion.fundaments.cloudand netnames such asNL-FUNDAMENTS-20080701. - The AS announces 33,536 IPv4 addresses across 30 prefixes and 7 IPv6 prefixes, while maintaining 123 observed neighbours. This ratio of moderate address space against a high number of peering partners indicates a role focused on hosting and business connectivity rather than pure transit or residential access.
Notable
- Registrants are consistent with the announcer, with the majority of prefixes registered to Fundaments B.V.; one prefix, 78.31.112.0/21, is registered to Site4U B.V. under the netname
SITE4U-NET. - The address inventory is finely subdivided into numerous /21 and /22 blocks, reflecting an internal corporate estate structure typical of a hosting provider managing distinct customer or service segments.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
