# Updating a Reverse DNS Record / PTR

The [MySAU portal](http://www.mysau.com.au) 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](http://www.mysau.com.au) and select **Services**. ![](https://cdn.document360.io/d809f158-d4f4-47ff-83d4-18d9c9f7a04d/Images/Documentation/image-1728441473450.png)

2. Select the server to which the IP address is allocated.

**Alternatively, you can reset the record back to default (sau-order-id.servercontrol.com.au.).**

**It is also generally recommended 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 a valid and fully qualified domain name.***
