The concept of nameservers is important to understand for the purposes of domain name management.
Nameserver information is basically like a "pointer", so that when a person types in a domain name into their browser, the browser knows where to go in order to download the Web page.
The domain name itself might be something like www.johndoe.com, but the nameserver information is a completely separate issue, and is determined by the company where you are hosting your Web site.
For example, when you first register a domain name, you might not have it pointed anywhere in particular. If you type the domain name in, you might get an automatically generated "parking page", which says something like "coming soon".
In this scenario, the company that you registered the domain name through has temporarily set the nameserver information to point to a specific set of server computers, which take any requests for the domain name, and route it to the parking page.
Example nameserver information:
NS1.HOSTINGCOMPANY.COM
NS2.HOSTINGCOMPANY.COM
If you register a new domain name through Optimum Online web hosting, and order web hosting along with it, the nameserver information is automatically pointed at the right location.
However, if you registered your domain name somewhere else, and want to order a Web hosting plan, you would need to "point" the domain name at Optimum Online web hosting. This is accomplished by logging into the account provided by your registrar, and updating the nameserver information, so that the domain name points to Optimum Online web hosting.
For example, if you went to webhosting.optonline.net, and went through the process of ordering a web hosting account, at some point you'd have to enter a domain name, either an entirely new one, or one that you've registered somewhere else.
If you indicate that you've already registered somewhere else, then part of the process of making your Web site active will involve pointing the nameservers at Optimum Online web hosting.
So when your SiteControl account is set up, you could log in, click on the Domain Name link, and then click on the My Name Servers link.
Then you would see the nameservers associated with your webhosting account. This information would be Optimum Online's web hosting nameservers, basically like your location in Internet space. You can't type it into a browser, but the Internet uses the nameservers to help locate and direct traffic.
In this case, the adns.cv.siteprotect.com is the nameserver for this webhosting account. If you had a domain name registered through a third party, then you would need to log in to your account, and "point" your domain name at these nameservers.
