If you have already registered a domain name and wish to access only website with us and not email and other services, then you need to create a Support ticket as soon as your hosting signup is finished, we will provide your an A record and a www record with IP details. You just need to contact your existing domain registrar / hosting provider and get that detail updated. Once you have updated the IP details, it takes only 1 to 12 hours to access your website from our servers.
