Summary
BackboneDirect
transit nsp netherlands hosting
DIEDERIK-AS is operated by BackboneDirect, a Dutch network service provider also known as Typno and SiteFast.
What it's used for
- The address space carries hosting and network service infrastructure, evidenced by netnames
BackboneDirect,SiteFast-NL, andTypnoassociated with the announced prefixes. - The AS announces 768 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 93 observed neighbours; this ratio of limited address space to high peering density indicates a transit or network service provider role.
- Traffic from this AS consists of web hosting, API endpoints, and backhaul connections for its European client base, consistent with its function as a Network Service Provider (NSP).
Notable
- Registrants align with the operator's brand identity, listing
Typno / BackboneDirectfor 45.152.39.0/24,Diederik Focko de Zeefor 89.37.98.0/24, andbackbone-direct-abuse-cfor 103.141.12.0/24. - The address inventory is small and fragmented, consisting of three distinct /24 blocks and a single /48 IPv6 prefix, typical of a specialized NSP rather than a large-scale residential ISP.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,768 prefixes, as published 2026-10-12. 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.
