Zone Editor

September 11, 2017     0 comments

Use the new Zone Editor interface to add, edit, and remove A, AAAA, CNAME, SRV, MX, and TXT DNS records. It performs all of the functions available in both the Simple Zone Editor and the Advanced Zone Editor in a simpler and easier to navigate interface.

(Home >> Domains >> Zone Editor)

Overview

DNS (Domain Name Service) converts human-readable domain names (for example, example.com) to computer-readable IP addresses (for example, 192.0.32.10). DNS uses zone files that reside on your server to map domain names to IP addresses.

Several different types of records reside in a domain's zone file. This feature allows you to create, edit, and delete the following records:

  • AAAA
  • CNAME (Canonical Name Record)
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance)
  • MX (Mail Exchanger)
  • SRV (Service Record)
  • TXT (Text Record)

Domains

This interface displays your account's domains. For each domain in the list, you can perform some actions directly. Click the text to perform that action.

To refresh the list of domains, click the gear icon and select Refresh List.

Manage Zone

This interface displays the zone records for the selected domain. To filter the list of zone records, enter a name in the text box, or select one of the record type filters.

Add a record

To add a record, perform the following steps: 

1. If this account owns more than one domain, click Manage next to the domain that you wish to modify.
  • Add A Record — This record maps hostnames to IP addresses. A records 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.

Note: 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.

  • Add AAAA Record — This record maps hostnames to IPv6 addresses. 
  • Add CNAME Record — 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 to an IP address.

  • Add DMARC Record — This record allows you to validate an email message's sender and filter spam and phishing email messages on your domain. If you select this option, the system creates a TXT record with a default DMARC record. The system also displays a form that allows you to specify the domain's DMARC policy (None, Quarantine, or Reject), as well as the following optional parameters:
2. Click the arrow next to  Add Record to select a record type:
  • Add MX Record — This record allows you to route a domain's incoming mail to a specific server. Changes that you make to a domain's MX (Mail Exchanger) control where the system delivers email for a domain.
  • Add SRV Record — 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.

  • Add TXT Record — This record contains text information for various services to read. For example, TXT records can specify data for the SPF, DKIM, or DMARC email authentication systems.

Note: The TXT record text box accepts invalid data and does not issue a warning.

3. Enter the appropriate information for the record type that you selected.

4. Click Add Record.

Edit a record

To edit a record, perform the following steps:

  1. If this account owns more than one domain, click Manage next to the domain you want to modify.

  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, click Manage next to the domain you want to modify.

  2. Click Delete next to the record that you wish to remove.
  3. Click  Delete i n the confirmation dialog box .

Reset zone files

Warning: This feature erases any modifications that you made to your zone records. The system attempts to save the domain's TXT entries. We recommend that you record any changes that you wish to save before you use this feature.

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, click Manage next to the domain that you wish to reset.
  2. Click the gear icon and select Reset Zone.
  3. Read the warning about the consequences.
  4. Click Continue to reset your zone, or Cancel to return to the Manage Zone interface.
