For each domain name, Plesk automatically creates a DNS zone in accordance with the DNS configuration presets that are changeable only by the server administrator. However, Plesk users allotted domain administration privileges can customize DNS zones for their own domains.
We would recommend modifying zones only to the users who have a good knowledge of DNS. Improper setup of DNS zone may result in improper functioning (or rather inaccessibility) of Web, mail, and FTP services.
If you use Plesk’s DNS service for serving the hosted domains, you may be interested in reading the sections Adding and removing resource records to/from the zones and Changing zone type. If you don’t, Plesk gives you the capabilities to validate zones on the authoritative DNS server against the hosting configuration of the domains served by Plesk. This is explained in the section If your Plesk is not authoritative for the zone.
To view and manage the zone for a specific domain, in the list of domains located at the bottom of your home page, click the domain name you need, and then click the DNS button under Services group.
The DNS zone properties screen will open.
From this screen you can:
To add a new resource record to the zone, select a record type and click Add. Then you will need to specify the data appropriate for the selected resource record type:
For an A record you will need to enter the domain name for which you wish to create an A record. If you are simply defining an A record for your main domain, then you should leave the available field empty. If you are defining an A record for a name server then you will need to input the appropriate entry for the given name server (ie. ns1). Then, you need to enter the appropriate IP address to which to associate the domain name.
For a NS record, you will need to enter the domain name for which you wish to create the NS record. If you are defining an NS record for your main domain, then you will leave the available field blank. Then enter the appropriate name server name in the field provided. You will need to enter the complete name (i.e. ns1.mynameserver.com).
For a MX record, you will need to enter the domain for which you are creating the MX record. For the main domain, you would simply leave the available field blank. You will then need to enter your mail exchanger, this is the name of the mail server. If you are running a remote mail server named 'mail.myhostname.com' then you would simply enter 'mail.myhostname.com' into the field provided. You will then need to set the priority for the mail exchanger. Select the priority using the drop-down box: 0 is the highest and 50 is the lowest. Keep in mind you would also need to add the appropriate A record, and/or CNAME if applicable for the remote mail exchange server.
For a CNAME record, you will need to first enter the alias domain name for which you wish to create the CNAME record. You then need to enter the domain name within which you want the alias to reside. Any domain name can be entered. It does not need to reside on the same server.
For a PTR record you will first enter the IP address/mask for which you wish to define the pointer. Then enter the appropriate domain name for this IP to be translated to.
For a TXT record, you will be able to enter an arbitrary text string, which could be a description or an SPF record.
To remove a resource record from the zone, in the list of resource records, select a corresponding check box, click Remove Selected, and then confirm removal.
To restore the original zone configuration by the DNS template, in the IP address drop-down box, select the IP address to be used with a template, specify whether a WWW alias is required for the domain, and click the Default button.
You can specify whether Plesk’s DNS server should act as a master or slave name server when serving a zone. A DNS master server stores locally the zone file it serves, while a slave server only retrieves a copy of this file from the master.
By default, when a new domain name is created, the Plesk’s domain name server is instructed to act a master for this zone. If you have another machine serving this zone as a master, and wish to make this Plesk server act as slave, you should switch the zone type to slave.
To switch the zone type from master to slave:
At the zone properties screen (Domain name > DNS) click
Switch icon. The DNS Zone Properties page will open and the DNS zone type will change to slave. Specify the IP address of the master DNS server.
Click Add.
To make the Plesk’s DNS server act a master for this zone, at the zone properties screen (Domain name > DNS) click Switch icon. The appropriate resource records for the zone will be restored as they were retained before you switched the zone type.
You should switch off the control panel’s DNS service for each individual zone served by external name servers. To do this, at the zone properties screen (Domain name > DNS), click the 
Disable icon. Turning the DNS service off for the zone will refresh the screen, so that only a list of name servers remains.
Note
The listed NS records have no effect on the system. They are only presented as clickable links on the screen to give you a chance to validate the configuration of the zone maintained on the external authoritative name servers through the control panel.
If you wish to validate the configuration of the zone maintained on the authoritative name servers:
Add to the list the entries pointing to the appropriate name servers that are authoritative for the zone: click Add, specify a name server, and click OK. Repeat this for each name server you would like to test. The records will appear in the list.
Click on the records that you just created. Plesk will retrieve the zone file from a remote name server, and check the resource records to make sure that domain’s resources are properly resolved. The results are interpreted and displayed on the screen.
