DNS FAQ

Domain Name System


Here's a concise collection of answers about the inner workings of the internet.

For instance:

What is DNS (Domain Name System)?


Websites have both a "friendly" address, called a Uniform Resource Locator (URL) and an IP address. People use URLs to find websites, but computers use IP addresses to find websites. DNS translates URLs into IP addresses (and vice versa). For example, if you type http://www.microsoft.com into the address bar in your web browser, your computer sends a request to a DNS server. The DNS server translates the URL into an IP address so that your computer can find the Microsoft web server.

Site Maps

Point the way



"As a Web designer and HTML builder, one of the first places I visit on a Web site is the site map. The site map shows an entire overview of the structure of the site, and more importantly, indicates how much effort was put into usability testing during the site's construction."

By Jim Kukral -Builder.com

According to Jakob Nielsen's
Alertbox Usability Study on Site Maps

"27 percent of users turn to site maps when asked to learn about a site's structure. If your site map is poorly designed, you may lose 27 percent of your Web visitors. That could translate into millions of dollars of missed sales for an e-commerce site, or a massive amount of missed leads for a service company."


(A Site Map is a guide to a web site used by visitors. A Sitemap is a file used by search engines to index entries on a site. )
