DNS is essentially a database of IP addresses. Each IP address is a series of numbers that allow computers to communicate with each other. A website is identified on a server by its IP address. Instead of your visitors having to remember an IP address to type into their browser to access your site, they instead use your domain name. When your domain is entered into their browser, DNS translates it into an IP address because that is what computers understand.Your computer is able to connect to your web hosting and show your website on the browser once the IP address is found.
New domain registrations can be added to a new or existing Netfirms account. Each Netfirms account includes 1 free e-mail account (unless you upgrade to a hosting package). If you are looking to register multiple domains and want an e-mail account for each, you can either create a separate Netfirms account for each domain or upgrade a single Netfirms account to a hosting package.
Before you sign up for Web hosting and start building a website, you need to buy the domain name where visitors will find your site. Hundreds of different registrars sell domains, so first and foremost, know that domain names work the same no matter which registrar you use. You don't need to buy your domain from the same company that will host your site. Aside from picking a registrar -- and, of course, your site's name -- you also need to pick a top-level domain like .com or .org.
