Adding IPs

To add IPs to a logical server:

1. Go to E.Manager -> Servers -> L.Servers.
2. Select the logical server from the list:

   

3. On the page that appears, enter the IP(s):

   

   • From: enter the first IP of the range of dedicated IPs. If you are adding only one IP, enter it here.
   • To: enter the last IP of the range of dedicated IPs.
   • Mask: enter the netmask -- you should have received it from your Internet Service Provider. When adding a pool of IPs on FreeBSD servers, add the first IP separately with the real mask, then add the other IPs as a pool with the mask 255.255.255.255.
   • Type: select the type of IP you are adding to the system:

     

   • Dedicated IP - the IP will be dedicated only to one site/service. This means that Dedicated IP should be unique and cannot be used anywhere else. Choose it only for Web and Windows servers.
   • Shared IP - the IP will be used by multiple Web sites under Unix and Windows via typical Virtual hosting. Choose it only for Web and Windows servers. Make sure to add shared IPs one by one, NOT as a range of IPs.
     Important: We recommend having at least one shared IP ("default" one with default Shared IP tag 2) on every Web/Windows server. This is in particular essential for creation of reseller DNS aliases.
   • Service IP - choose it for logical servers other than Web and Windows. Don't choose it for Web and Windows servers!

     Note:
     1. For every logical server other than Web/Windows exactly one service IP must be set!
     2. If you add a service IP to a logical server in the "Control Panel" or "MRTG" group, make sure it is the IP of the physical server.
     Mind also, that service IP doesn't automatically bind to a physical server. Instead you have to put it up manually or use physical server's primary IP.

   • DNS Reseller IP - choose it only for resellers' name server aliases.
   • System Management IP - reserved for future use. Don't select it.
   • Outgoing IP - configure separate IP for sending outgoing mail. If this value is specified, all your mail is sent from the specified IP, not from your actual mail server IP. Use this control when your mail server IP is added to a spam blacklist, and mail from your domain is rejected. Important: You can have only one Outgoing IP per mail server.
   • Bouncing IP - configure separate IP for sending bounced mail. It allows isolating bounced message on a different IP address and block them without blocking other mail. Important: You can have only one Bouncing IP per mail server.
   • Shared IP Tag: a digital "mark" that helps to separate sites on one logical server. It allows you to allocate a separate shared IP address to a group of sites of, say, explicit nature. This may become necessary, because many corporate firewalls filter sites based on their IP address, not domain name. Note: Make sure to have one shared IP tag used by one shared IP within one logical server.

     IMPORTANT:
     1. Make sure the same dedicated or shared IP is not used by more than 1 server.
     2. When added to the logical Web server, dedicated IPs are not registered in ipconfig. They are only added when new accounts are created.

4. Added IPs will show up under IPs in the Logical Server section.

Once added, IPs can be painlessly changed only when no Websites are running on the system. Changing IPs on production servers implies an IP migration.
