No problem, If you already have a domain name registered and if you want to use our web hosting services, we will mail your our "domain namesevers" (DNS) and so you can login to your domain name registrar's control panel and change the existing domain nameservers to our DNS. Usually the following but it can differ depending on the sever you gonna get.

NS1.GOVIPHOSTING.COM
NS2.GOVIPHOSTING.COM
