About this network

The AS handle CK-IT-AS is held by Ck IT Solutions.

What it's used for

• The address space carries hosting services, evidenced by the netname NET-146-103-47-0-24 and reverse DNS entries pointing to hosted-by.surfhosting.nl.
• The network announces 256 IPv4 addresses across 1 prefix and 3 IPv6 prefixes, while maintaining 27 observed neighbours. This ratio of limited address space against a high number of peers indicates a transit or interconnection-heavy role rather than a large access network.
• Traffic from this AS consists of web and API endpoints for hosted clients, consistent with the operator's business as an IT solutions and hosting provider.

Notable

• The RDAP registrant for the announced IPv4 prefix is Ck Hosting, which aligns with the announcer Ck IT Solutions and the reverse DNS domain surfhosting.nl.
• The address inventory is compact, consisting of a single /24 block for IPv4 and three /48 blocks for IPv6, suggesting a focused, small-scale hosting operation.
