  • TTL — The DNS entry's TTL.
  • Record Type — The DNS record type.

Warning

The Class value for each DNS zone must be IN.

Record Type

The following table lists the most common DNS record types:

Record TypeDescriptionDetails
SOAStart of Authority record.

Contains authoritative information. Authoritative information includes the following information, on record with an accredited domain name registrar:

  • The authoritative nameserver’s hostname.
  • The server administrator’s contact email with a period (.) in place of the @ character.
  • The following time-related data:
    • The serial number, which includes the year, month, date, and time at which you last edited the record.
    • The time interval during which clients wait before they refresh zone data.
    • The time interval during which clients wait before they try again after a failed refresh attempt.
    • The time interval after which the record is no longer authoritative.
    • The minimum TTL.
NSNameserver record.Specifies the hostname that clients use to search for the domain.
AAddress record.Matches the domain name to an IP address. 
MX  Mail Exchange record.Matches the domain name to a list of servers that handle mail for the domain, and tags each server with a priority (the highest priority is 0).
CNAMECanonical name record.

Matches the domain name to an alias. Use this record type to run a server that is not an Apache server, such as an FTP server, on a separate port.

Add entries

Use the empty text boxes below the Add New Entries Below this Line heading to add new entries to the DNS record.

Warning:

You must configure your DNS records correctly to allow visitors to access the domains.

When you have entered the desired information, click Save.

How to set a separate IP address for the domain and mail server

If you change the IP address of the domain's A record, your mail server's IP address also automatically changes. This happens because the standard zone template uses a CNAME record to point the mail server to the A record of a domain.

To assign a different IP address to the mail server, perform the following steps:

  1. Change the MX record value to mail.$domain., where $domain. represents the domain. For example, change example.com. to  mail.example.com.

    Important:

     You must include the trailing period after mail.example.com. 

  2. Select CNAME from the Record Type menu.
  3. Click Save.

To change the zone template so that all new domains create MX records that assign your mail server a different IP address, use WHM's  Edit Zone Templates  interface ( Home >> DNS Functions >> Edit Zone Templates ).
