About this network

THREE-W-INFRA-AS is operated by 3W Infra B.V.

What it's used for

• The address space carries infrastructure for a private Infrastructure-as-a-Service (IaaS) provider, evidenced by netnames such as NL-3W-INFRA-20190807 and reverse DNS entries like alfa.ams01.3winfra.com.
• The AS announces 10,496 IPv4 addresses across 14 prefixes and 52 IPv6 prefixes, maintaining 136 observed neighbours; this ratio indicates a hosting and interconnection role rather than a large-scale residential access network.
• Traffic from this AS consists of web and API endpoints, dedicated servers, and colocation services for business clients, consistent with the operator's focus on low-latency interconnection and infrastructure hosting.

Notable

• Registrants for the majority of prefixes align with the announcer, listing NOC 3W Infra; 3W Infra B.V., while a subset of prefixes are registered to UA-Hosting SIA and Isimtescil Bilisim A.S., indicating leased or acquired address space.
• The inventory is subdivided into multiple /22 and /24 blocks, reflecting a segmented corporate estate for different service tiers or customer segments.
