DNS Servers: When you type a domain name into your web browser (e.g., “www.Broadband-speedtest.info”), computers called “Domain Name Servers” attempt to quickly translate that domain name into a series of numbers called an IP address that your computer can understand. This is necessary for the website content to be located, requested and then delivered back to your browser.
DNS Servers are one of several components which help make your connection truly “fast”. If these servers aren’t functioning or are slow to respond, it can make your connection appear slow or even offline. Make sure your provider has both secondary and primary DNS servers for you to use. Do your own investigation. Try ‘Googling’ your provider’s name and DNS to see if they have a history of problems, (e.g., search for “DNS Comcast”).
