Modifying Resource Records

To modify the properties of a resource record:

  1. Click the Domains shortcut in the navigation pane.
  2. Click the domain name you need.
  3. Click the DNS icon.
  4. Click the hyperlink in the Host column corresponding to the resource record you want to modify.

To modify the entries in the Start of Authority (SOA) record for a domain:

  2. Click the domain name you need.
  3. Click the DNS icon.
  4. Click SOA Preferences.
  5. Specify the desired values:
  6. Click OK.

Usage of serial number format recommended by IETF and RIPE is mandatory for many domains registered in some high-level DNS zones, mostly European ones. If your domain is registered in one of these zones and your registrar refuses your SOA serial number, using serial number format recommended by IETF and RIPE should resolve this issue.

Plesk servers use UNIX-timestamp syntax for configuring DNS zones. UNIX timestamp is the number of seconds since January 1, 1970 (Unix Epoch). The 32-bit timestamp will overflow by July 8, 2038.

RIPE recommends using YYYYMMDDNN format, where YYYY is year (four digits), MM is month (two digits), DD is day of month (two digits) and NN is version per day (two digits). The YYYYMMDDNN format won't overflow until the year 4294.

To change the Start of Authority (SOA) serial number format to YYYYMMDDNN for a domain:

  1. Click the Domains shortcut in the navigation pane.
  2. Click the domain name you need.
  3. Click the DNS icon.
  4. Click SOA Preferences.
  5. Select the Use serial number format recommended by IETF and RIPE check box.

    Note: See the sample of SOA serial number generated with the selected format. If the resulting number is less, than the current zone number, the modification may cause temporary malfunction of DNS for this domain. Zone updates may be invisible to Internet users for some time.
