If you do not want to use our Nameservers and you want to create your own A-Record for your domain name, please follow the steps below.
1) Be sure that you've mapped your domain name to your account. (See this article on how to map a domain name
2) Login to your control panel, go to "Hosting Control Panel" -> "DNS Manager"
3) In the DNS Manager, you'll be able to see existing A record for your domain names. You can simply use the same IP we have in there and create your own A record in your current domain registrar.
