### Simple: Adding Hostnames and Name Servers

Important Note: The changes to the zone file that can be made as this described below in this section are being saved both in the zone file itself and the HSPcomplete database. This means that hostnames added using the Hostnames tab are visible and manageable by the HSPcomplete web-based interface and can be used by customers to create websites and mailboxes in the Control Panel.

To add a sub-domain to a registered domain:

1. Select Service Director - Domain Manager - Domains.
2. Select the domain by clicking on its name. As a domain details will be displayed, click the Hostnames tab.
3. Fill the form that appears:
   1. Type the sub-domain name into the Hostname field.
   2. You can assign the newly created hostname (i.e., a sub-domain) to particular VE. To this effect, set the radio button to this option and click the Select button to chose VE from the list.
   3. Or select the IP address a new hostname will be mapped into from the IP address drop-down menu.
   4. You can assign external IP address to this hostname (set radio button to this and type the IP address).
4. Click the OK button.

You can leave the new hostname unassigned and do this later. To this effect, you will need to select a domain, click the Hostnames tab, and select (click on it) the needed hostname from the list. However, if you want to refer to one of your VEs by the new hostname, it is necessary to assign this hostname.

Note: When you are creating a new hostname, a new MX record that points to this host is being automatically created.

When a new hostname is created (by staff member, using Domain Manager or by a customer, using Control Panel), a virtual host is being automatically added.

To delegate a sub-domain to a new name server:

1. Select Service Director - Domain Manager - Domains.
2. Select the domain by clicking on its name. As a domain details will be displayed, click the Name Servers tab. The list of name servers responsible for a domain zone file appears.
3. Click the New Name Server button.
4. Fill the form that appears:
   1. Set the option button to the name servers set you want to select a name server from.

      Note: The set of name server sets available is subject to the settings made in the Domain Manager - Name Servers Sets.

   2. Select the name server from the relevant drop-down menu.
   3. Repeat steps a - b to select more name servers.
5. Click the Save button. The list of name servers appears.
6. To bring the changes made in correspondence with the domain Registrar's information, you can check the box next to the name server(s) name(s) and click the Synchronize Registrar button.

Note: Actually, the HSPcomplete automatically synchronizes the name server set with a Registrar each time you are adding or detaching a name server. However, in some cases you may need to repeat the synchronization manually. For example, if a Registrar (such as RU-Center) does not allow to assign only one name server to a domain, the synchronization will fail, i.e., the "lonely" name server will be saved in the HSPcomplete database, but there will be no records about this at Registrar. In this case, you can assign one more name server to a domain and repeat the synchronization using the Synchronize Registrar button to synchronize both the previously and newly added name servers.
