How to change my A record?
You can manage your domain’s A records from your cPanel.
In order to do this under CPanel, please use the Simple DNS Zone Editor tool to make the necessary changes in the DNS zone for the selected domain name. For WSP, please go to your domain, click on the domain name, then click on EDIT DNS Zone.
If you have problems changing your A record, try contacting your web host for assistance. You can always contact Support for such problems.
