About this network

The AS handle UNISERVER-AS is held by Uniserver Internet B.V.

What it's used for

• The address space carries hosting and business infrastructure, evidenced by netnames such as NL-DUTCHCLOUD and NL-UNISERVER, and reverse DNS entries like hosted.by.denit.net and hosted.at.uniserver.nl.
• With 57088 IPv4 addresses announced across 36 prefixes and 112 observed neighbours, the ratio suggests a hosting or business network rather than a pure transit provider.

Notable

• Registrants include both Uniserver Internet B.V. and Denit B.V., with netnames reflecting both Uniserver and DutchCloud branding, indicating a shared or merged operational history.
• The address inventory is finely subdivided into multiple /20, /21, and /22 blocks, consistent with an internal corporate estate or multi-tenant hosting environment.
