Posted by Jamison on 23 10 2015.

Getting yourself familiar with the Domain Name System or DNS is essential to understand how your website and the Internet functions. Simply put, DNS is a database, which links host names such as http://www.buycpanel.com, to a specific IP address like 192.168.124.1. This is the simplest and most straightforward definition of DNS, but it has many various features in addition to linking host names to IP addresses.

 

DNS acts like a contact list for the Internet. DNS makes knowing and categorizing information online easier. For easier navigation, the Internet mostly relies on DNS.

DNS Zones

 

DNS is divided into zones. These zones store name information about the DNS domains. Zones are the source of information about the domain for each DNS domain name included in the zone. A zone begins as a database for the storage of a single DNS domain name. If other domains are put below the domain utilized to create the zone, the domains are either part of the same zone or another zone.

 

Part of the name server’s function is to find the server and the exact DNS zone. It does this to gather the following information.

 

  • A Record – directs your domain/subdomain to an IP address (i.e. website name → website IP address)
  • CNAME Record – redirects your domain/subdomain to another domain (i.e. buycpanel.com → buycpanel.com)
  • MX Records – makes sure you receive emails where you want them
  • NS Records – must match the used name servers

 

Advanced users can manage DNS Zones through WHM and some functions are also available on cPanel.

 

If you want to change your NS records while using private servers, follow these steps:

 

  1. Log into WHM.
  2. Expand DNS Functions.
  3. Click Edit DNS Zone.
  4. Select domain name and click the Edit button.
  5. Replace the name server with your primary private name server.
  6. Replace each name server with your private name servers.
  7. Click the Save button at the bottom of the page.

 

You can use both cPanel and WHM to point MX Records to a remote or local server.

In WHM

 

  1. Log into WHM.
  2. Expand DNS Functions.
  3. Click Edit MX Entry.
  4. Select the domain name you want to change and click Edit.
  5. Select Local, Backup or Remote Mail Exchangers. Choose Automatically Detect Configuration if you are unsure, and click Change. Select where the MX Records will be pointed, click Save.

 

In cPanel

 

  1. Log into cPanel.
  2. Under Mail, click on MX Entry.
  3. Select Local or Remote Mail Exchangers.
  4. Click Change to finish.

 

Managing your DNS is essential to having you information all at the correct place and address. Making your site organized, easy to find and navigate will help you improve your site performance.
