Configuring and Maintaining Your Server 55
Adding and Removing IP Addresses
After installation, Plesk reads all your IP addresses from the network configuration files
and can then use these IP addresses for hosting DNS domains and Web sites.
When you obtain a new IP address that you would like to use on the server, you should
add the address through the control panel, as Plesk might not recognize manual
modifications you make to the network configuration files.
With Plesk you can mark all your IP addresses as shared or dedicated before you
assign them to your customers. This allows the control panel to distinguish between
them and not to let you assign a dedicated IP address to several customers at once. A
dedicated IP address can be assigned to a single customer, while a shared IP address
can be shared among several user accounts.
Note that SSL protection with authentic digital certificates and Anonymous FTP
services are available only to dedicated hosting accounts on a dedicated IP address.
Shared hosting accounts can also have SSL protection, but visitors to such protected
sites will get error messages in their browsers.
Note: in this version of Plesk control panel, dedicated IP addresses are referred to as
Exclusive IP addresses.
To view the IP addresses you have at your disposal:
1 Go to Server > IP Addresses.
Your IP addresses are listed and the following supplementary information is given:
An icon in the S (Status) column shows if your IP address is properly
configured on the network interface. If your IP address was removed from the
network interface, an icon will show .
An icon in the T (Type) column shows if an address was allocated to a single
customer as a dedicated IP address, and if an address is shared among
many customers.
The IP address, Subnet Mask and Interface columns show which IP addresses are
on which network interfaces.
The Clients column shows the number of user accounts who you assigned a
given IP address. To view the users by names, click the respective number in
the Clients column.
The Hosting column shows a number of web sites hosted on an IP address. To
view the domain names of these web sites, click the respective number in the
Hosting column.
