Dedicated server (ubuntu) with an ip block without an vrack

Hello,

I got a dedicated server with ubuntu installed as OS and its running Virtualizor. I would like to host VPS systems on here, so you would like to configure the extra ip block i got for the dedicated server. But i cant seem to find a decent tutorial or documentation on how to configure this.

Is there someone who can help me get this configured?

Hope to hear from someone soon!

Kind regrads,
Robin
