Plesk Panel or just Plesk in short is known as one of the most multi-functional Control Panels. It goes far beyond the capabilities of the regular web-based tools for managing the server resources your sites need to exist. Plesk is a complete multi-level hosting platform Control Panel, giving the server administrator a wide range of graphic-interface options to set up and maintain a whole hosting business serving the end customer. It is just as good for configuring shared hosting solutions as it is for setting up VPS and dedicated servers. The operating systems supporting Plesk include Fedora, Red Hat, Debian, FreeBSD, SuSE, CentOS, Ubuntu, and Windows.

Lets see how to make DNS changes in Plesk

Once you have logged into your Plesk account the main screen with options like Report, Limits, Preferences, Domain Aliases, Domain User, Register, etc appear. Click on the DNS under the Services section.
Once entered the DNS zone for the specific domain, you see all the DNS zones that have been automatically created in Plesk.

Step 1 : Click on the zone settings from the 3 tabs that are mentioned on the top of the screen viz, General, Zone setting and Transfer Restrictions.
This page allows you to adjust the default TTL (time to live) for all DNS records and following SOA record parameters for the current domain:

SOA Options –

Refresh Interval – This parameter defines the amount of time that should pass from the moment when a secondary name server gets a copy of the zone (or sees that it hasn’t changed ) before it checks to see if it needs a new copy.

Retry Interval – This parameter defines the amount of time that the primary name server(s) should wait, if an attempt to refresh failed, before making another attempt to refresh.

Expire Interval – This parameter defines the amount of time that lets the secondary name server(s) know how long they can hold the information before it is no longer considered authoritative.

Minimum TTL –
This parameter defines the amount of time that the records in the zone are valid for (time-to-live or TTL), unless the records have a higher TTL value.

To edit the DNS zone settings for the selected domain, type desired values into each input field and select the appropriate time units from the corresponding drop-down list.

Step 2 : Once the desired fields are edited, click the Set tab

Step 3 : Domain Restriction page is designed for managing the common Access Control List (ACL) that contains all hosts to which DNS zone transfers for all zones are allowed.
To add an entry to the list, in the IP address/mask input fields, enter the IP address or the network address selecting the appropriate subnet mask from the drop down list to the left of the input fields, and click Add Network.

*Note: DNS is a complicated issue. Be sure you know what you are doing before you edit any settings – other wise you could compromise your site’s connectivity.
