AS50917 announces 3 IPv4 prefixes covering 768 addresses and 2 IPv6 prefixes.

About this network

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, and Typno associated 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 / BackboneDirect for 45.152.39.0/24, Diederik Focko de Zee for 89.37.98.0/24, and backbone-direct-abuse-c for 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.
