SOA (Start of Authority) Record

Each Zone contains a single SOA Record, which holds the following values for the Zone:

  • Name of Primary DNS Server: The domain name of the Primary DNS server for the Zone. The Zone should contain a matching NS Record.

  • The mailbox of the Responsible Person: The email address of the person responsible for maintenance of the Zone.

  • Serial Number: Used by the Secondary DNS servers to check if the Zone has changed. If the Serial Number is higher than what the Secondary server has, a Zone Transfer will be initiated. This number is automatically increased by our DNS servers when changes to the Zone or its Records are made.

  • Refresh Interval: How often the Secondary DNS servers should check if changes are made to the zone.

  • Retry Interval: How often the Secondary DNS server should retry checking if changes are made if the first refresh fails.

  • Expire Interval: How long the Zone will be valid after a refresh. Secondary servers will discard the Zone if no refresh could be made within this interval.

  • Minimum (Default) TTL: Used as the default TTL for new Records created within the zone. Also used by other DNS servers to cache negative responses (such as Record does not exist, etc.).
