Advanced DNS Zone Editor

Overview

DNS (Domain Name Service) is the component of the Internet that converts human-readable domain names (for example, example.com) into computer-readable IP addresses (for example, 195.1.326.12). DNS uses zone files that reside on your server to map domain names to IP addresses.

There are several different types of records in a domain's zone file. This feature allows you to create, edit, and delete A, AAAA, CNAME (Canonical Name Record), SRV (Service Record), and TXT (Text Record) records.

Reset zone files

To reset your DNS zone files to the defaults that your hosting provider specifies, perform the following steps:

1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.

2. Click more.
3. Select the Are you sure that you wish to erase all of your entries and revert to the default state? checkbox.
4. Click Reset Zone File.

Add a Record

To add a record, perform the following steps: 

1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.

2. Select a record type:

   • A — This record maps hostnames to IP addresses. A records are essential because they allow DNS servers to identify and locate your website and its various services on the Internet. Without appropriate A records, your visitors cannot access your website, FTP site, or email accounts.

     Remember

     cPanel configures your DNS records so that visitors can resolve your website and its services, such as FTP and email. Only add A records when you add a service that cPanel & WHM or your service provider does not provide.

   • AAAA — This record maps hostnames to IPv6 addresses. 

   • CNAME — This record creates an alias for another domain name, which DNS looks up. This is useful, for example, if you point multiple CNAME records to a single A record in order to simplify DNS maintenance.

     Note:

     You cannot point a CNAME record at an IP address.

   • SRV — This record provides information about available services on specific ports on your server.

     Note:

     The SRV record must point at a hostname with an A (or AAAA) record. You cannot point an SRV record at a CNAME record.

   • TXT — This record contains text information for various services to read. For example, TXT records can specify data for the SPF (Sender Policy Framework) or DKIM (Domain Keys Mail Identifier) email authentication systems.
3. Enter the appropriate information for the record type that you select.
4. Click Add A Record.

Edit a record

To edit a record, perform the following steps:

1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.

2. Click Edit next to the record that you wish to edit.
3. Change the information in the text boxes as necessary.
4. Click Edit Record to save your changes, or click Cancel to discard them.

Delete a record

To delete a record, perform the following steps:

1. If this account owns more than one domain, select the domain that you wish to manage from the Domain menu.

2. Click Delete next to the record that you wish to remove.
