About this network

The AS handle VITRUMNET is held by VitrumNet BV.

What it's used for

• The address space carries business and fiber infrastructure, evidenced by the reverse DNS record 85-119-109-254.sdb.prolocation.net and netnames referencing "Stichting Breedband Drechtsteden" (Broadband Foundation Drechtsteden).
• The network announces 4096 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 34 observed neighbours. This ratio of modest address inventory against a significant number of peering relationships indicates a transit or interconnection role rather than a large-scale residential access network.
• Traffic from this AS consists of business endpoints and fiber backhaul for the Drechtsteden region, supporting the broadband infrastructure managed by the associated foundation.

Notable

• Registrants for the largest prefixes include both VitrumNet BV and Stichting Breedband Drechtsteden, indicating a close operational relationship or shared management of the address space.
