Domain Name System

With out the DNS service there is no Internet. Your Internet Service Provider (ISP) has two main parts. The connectivity and resolving name server, or rDNS. This allows you to find websites and services. Not to be confused with a search engine which lets you search for specific content. Something more basic, it allows you to view YouTube, WordPress.org or Facebook.

Name Servers

When you buy a domain from a registrar they provide a DNS service. This service allows you to connect your domain to a host, website and a lot more.

You get your own Internet Address book for your domain. This allows you to setup email services, websites, and almost endless sub-domains.

The main thing you want to get from your hosting is the IP address of your server. Once you have that you can change the A or AAAA record for your domain. So when you type in your domain, the system can locate the right server. The last thing your site needs to work is for the server configuration to point to the right area. A server that gets a connection requesting your domain needs the right directory to point to.

It’s important to know which directory your website will load from so you know where you should upload or install your website to.

Once connected on both ends your site will go live.
