About this network

IN4U-AS is operated by Netrics AG.

What it's used for

• The address space carries a mix of Netrics infrastructure and leased blocks for third-party Swiss businesses, evidenced by netnames such as CH-IN4U-20070410, CH-COMPARIS-NET, UNIC-VASP, and NEOLOGIC-NET.
• With 14,592 IPv4 addresses announced across 14 prefixes and 124 observed neighbours, the high neighbour-to-address ratio indicates a transit and hosting role rather than a large-scale access network.

Notable

• Registrants largely align with the announcer, with Netrics AG holding the majority of blocks, while specific prefixes are registered to customers like Decisis Services AG, Unic AG, and Neologic Software AG.
• The inventory consists of a few large /20 and /22 blocks alongside numerous smaller /24 allocations, reflecting a diverse customer base within the Swiss market.
