What is DNS and what does DNS do?

What is DNS?

The Domain Name System (DNS) , in my opinion, controls the internet! Others refer to it as

  1. The phone book of the internet
  2. The traffic light system of the world
  3. The air traffic control system for the web

Why is DNS Important?

The key function of the DNS is to assign domain names to IP addresses of devices on the internet

Without DNS, you would have to type in every time you wanted to visit and when you wanted to stalk your Facebook friends

Imagine that!

Where can I purchase a DNS service?

Most people prefer to let the techs handle DNS but if you do want to handle it yourself, most domain and hosting companies provide a DNS service

Managing DNS is technical and requires 100% accuracy so unless you’re familiar with it, leave it to the experts

How do I manage my DNS?

The key components of a DNS service are below. Each ‘record’ resolves to an IP address where that service is located

  1. Nameservers – –
  2. www records – –
  3. A records – –
  4. MX records – –

How can I test my service?

  1. Start -> Run or hold the “windows” key + “r” at the same time. Type “cmd” and click “ok”
  2. Launch the Terminal, found in the Utilities folder of Applications (Mac)
  3. You should see “C:Usershome>”
  4. Type “ping” and press enter
  5. Wait a few moments
  6. Now you should see
