Hello Masui,
We welcome your interest in our services. Eukhost provides fully
managed dedicated servers. This includes any installations or customer configurations you want to be done, performing security configurations and server hardening in general, resolving any technical issues you come across. We also install System Integrity Monitor to supervise the essential and key services on your server.
Depending on the OS platform you wish to go with, you may refer to
Linux Server Management or the Windows Server Management Functions
You can set rDNS for every IP which is binded on your server. You just have to inform the technical support team with the IP and domain details.
