We are using a dedicated hosting server from a hosting provider.
When we do a ping -a xxx.xxx.xxx.xxx (our IP address of the server) we receive unassigned.hostingprovider.net (where hostingprovider.net is the name of the provider). we would like to change this that the reverse ping replies with plesk.domain.com (where domain.com is our own domain name).
I've already changed the hostname in the plesk interface, but this doesn't change this.
Does anyone know how to change this name? or how to disable this that it doesn't return a host name?

 

You will have to contact your provider to have the rDNS (in.addr-arpa) changed, you cannot do this from Plesk itself, it is outside of control of plesk.
