How can I add or update A Records in my Wix account?
An A or address record is a DNS record that can be used to point your domain name and host names to a static IP address. You can add or update your A records from the Domains page of your Wix account.
To add or update an A record: Sign in to your Wix account > from the top menu, hover over Subscriptions > click Domains > under My Domains, next to the relevant domain, click Manage.
Under Domain Summary, select the Advanced tab > next to DNS Records, click Manage > next to A (Host), click Add a new A record to add or click the pencil icon to edit > enter the information in the pop-up window > click Save.
If your domain is connected to your Wix site via Pointing, your domain host is in control of your A records.
