The MySAU portal allows you to update a reverse DNS record for any IP addresses allocated to your Dedicated Server or Colocation Services.
1. To make an update, log in to the portal and select Services.
2. Select the server to which the IP address is allocated.
3. Select Reverse DNS from the side menu.
4. From there, you can update the record by clicking on "Edit":
Alternatively, you can reset the record back to default (sau-order-id.servercontrol.com.au.). It is also generally wise to ensure you have an A record pointing back to your IP address, which matches your Reverse DNS Entry.
NOTE: Ensure you have a full stop at the end of your new record so that it is valid.
