AS39521 announces 37 IPv4 prefixes covering 20,736 addresses and 3 IPv6 prefixes.

About this network

TNGNET is operated by TNGNET B.V., a Dutch provider of enterprise connectivity, cloud, and colocation services.

What it's used for

• The address space carries infrastructure and enterprise traffic, with netnames like NL-TNGNET-20120504 and IPXO-LLC indicating a mix of owned and leased IP blocks.
• The AS announces 20,480 IPv4 addresses across 37 prefixes and 3 IPv6 prefixes, while maintaining 110 observed neighbours; this ratio of moderate address space to high peering density indicates a transit or interconnection role rather than a large-scale residential access network.
• Traffic from this AS consists of enterprise-grade connectivity, cloud workloads, and colocation services, supporting diverse fiber connections and access to Tier-1 networks and major Internet Exchange Points.

Notable

• Registrants for the largest prefixes include TNGNET B.V. and IPXO LLC, with some blocks registered to Private Customer, reflecting a combination of direct ownership and third-party IP leasing.
• The address inventory is fragmented across multiple /22 and /24 blocks, including ranges from 5.22.204.0/22 to 82.22.143.0/24, which is typical for an infrastructure provider aggregating diverse IP resources.
