Assign a remote server's IP to another server location

How we can assign a remote IP address to another server?

I have a VPS in Germany (Mikrotik RouterOS installed) and it has a valid IP address,

And in other side in Italy, I have another server which has installed Vmware ESXi (Installed CentOS VM & a Mikrotik Router OS inside it)

I want to assign and use the Germany IP address in Italy Server (CentOS) How can I do this ? I can use Mikrotik or any other solution using ESXi or Centos

Thank you

The only way I think this is possible is by using a VPN link between countries and then route that IP down the VPN link
