There are 2 different method to point a domain to your hosting:
1 - User our DNS servers on your domain
This is the easiest and the recommended method. For a domain to point to your hosting account you simply need to configure our Hosting DNS servers on it:
dns2.guebs.com dns3.guebs.com dns4.guebs.com
Take into account that DNS changes are not inmediate, you will have to wait between a few minutes and several hours ( usually up to 48 hours ).
2 - Create a CNAME pointing to the alias domain
Every hosting account has an alias domain like gstrhx6ag.gclientes.com assigned to it. You can use that domain as an alternative to your real doman name to navigate your website or to connect via FTP.
If you don't known the gclientes.com domain assigned to your hosting account, just check your hosting account's basic details.
Suppose that your real domain is lifeatfter60.com and that your alias domain is gstrhx6ag.gclientes.com. In order to host the website with us you should create the following DNS records:
lifeatfter60.com. IN A 220.127.116.11 www.lifeatfter60.com. IN CNAME gstrhx6ag.gclientes.com.
If you do also want to host the email service in the hosting account, create the following DNS records:
lifeatfter60.com. IN MX mail.lifeatfter60.com. mail.lifeatfter60.com. IN CNAME gstrhx6ag.gclientes.com.
