PLESK 7.5 FOR WINDOWS > Performing Administrative Tasks

Managing Server IP Addresses

If your server has more than one IP address or is on more than one network interface, you can use the IP Addresses function in order to control IP addresses on system network interfaces.

To do this, click the IP Addresses icon on the Server administration page. The IP addresses management page appears displaying the list of IP addresses available in the system.

The icons in the S and T columns represent the IP address state and type ( exclusive or shared) respectively, the numbers shown in the Clients and Hosting columns indicate whether the ip address is used by clients and hosting accounts.

NOTE

You can allocate IPs as either exclusive, meaning that a single user obtains the exclusive rights to this IP, or shared, meaning that this IP is shared among many clients (i.e. one IP can be used for hosting by many clients).

At this page, you can add and remove ip addresses, refresh the list of ip addresses, access ip properties editing.

To remove an IP from the network interface, select a checkbox corresponding to the IP you wish to remove, and click Remove Selected.

NOTE

You cannot remove the main interface IP from the Plesk control panel; the corresponding checkbox appears as disabled.

IMPORTANT

When the new IP addresses appear on the interface, but are not displayed in the control panel, you may have to refresh the list of IP addresses manually. To do this, click Reread IP.

Adding a new IP address

To add an IP to a Plesk managed server, follow these steps:

  1. On the IP addresses management page, click the Add IP Address icon. The IP address adding page will open.

  2. Using the Interface drop-down box, select the network interface the IP will be added to. Specify the appropriate IP address and Subnet Mask in the input fields provided. Define the IP address type (Shared or Exclusive) and select the SSL certificate to be used for the hosting accounts created using this IP.

  3. Click OK to submit. Once submitted, the new address remains on the screen to facilitate the entry of multiple addresses.

NOTE

You cannot add random IP addresses; they must be assigned.

Editing the IP address properties: changing the IP type, assigning a SSL certificate to an IP, repairing an IP

  1. At the IP addresses management page, select the ip address you wish to edit. The IP editing page will open.

  2. To change the IP address type to Shared or Exclusive, select the respective radio button.

  3. To assign a SSL certificate to the IP, select the required SSL certificate from the drop-down list of certificates available from the repository.

  4. In case if an IP address is missing on the interface, try restoring it using the Repair IP icon.

  5. Click OK to submit your changes.

Selecting a 'default domain'

The default domain seen in the IP properties is the domain, which has the highest priority defined in the web server configuration file over all domains using the given ip address for hosting. This means that all requests coming to the IP address and not recognized by Web server will be directed to the virtual host of the domain selected as default. If the default domain does not have physical hosting configured or the default domain is not assigned to the IP address, the request will be directed to the default virtual host. This feature allows accessing a domain by specifying an IP address in the address bar of the web browser.

To assign the default domain for the given IP address, follow these steps:

  1. At the IP addresses management page, click on the number in the Hosting column of the list, corresponding to the necessary IP address. The page will open displaying the list of domains hosted using this IP address.

  2. Select the domain using the corresponding radio button.

  3. Click Set as Default. Now the default domain is assigned.

Accessing the list of clients sharing the same IP address
