DNS Basics

What is DNS?

Domain Name System – This is an Internet system that relates domain names into IP addresses. DNS can be considered something similar to a phone book. When you move from one location to another, your name stays the same, but your phone number may change. In order to point your name to the new phone number, you must contact the telephone service provider so they assign you the new phone number and update all directory information to reflect you as pointing to this new phone number. In this way, the IP address can be compared to a phone number: When someone calls http://www.example.com/, your ISP looks at the DNS server, and asks “how do I contact example.com?” The DNS server responds: “It can be found at 198.105.232.4″. As the Internet understands it, this can be considered the phone number for the server, which houses the http://www.example.com web site.

The DNS records for your domain are kept on a name server in a place called a DNS zone. When you register a domain by means of the control panel, all DNS records are automatically created for you, but in some cases you may need to setup custom records to your DNS zone. An example would be when you want all email to be processed by an external mail server rather than by the built-in mail system. However, such user intervention requires knowledge of DNS configuration and clear understanding of what is to be done.

How can I remove default DNS records?

The first step is to log onto your control panel.
Once you are logged in you will then want to click on the “Domains” icon:      domains

After clicking on the domains icon you will then see a page listing all of the domains you have added to the control panel. Click on the domain that you want to delete the custom DNS records for:cpclickdomain

Next you will see the “Edit Domain” page. Here there will be an option to edit DNS configuration:

editdns

After clicking the “EDIT” button you will be taken to a screen that shows you your current DNS settings as well as gives you the option to add custom DNS records. In order to delete any of the DNS records you can simply click on the trash can icon to the right of the default record: DNSconfigdel

When changing DNS your site may become unavailable due to propagation. Average down time is around 24-48 hours but can take up to 72 hours to complete in some cases.
