I am not talking about the one from that fruity company. Your MAC address is the identifying agent for your computer's network card. It is a critical component for proper routing of network traffic. It gets what you want, and sometimes don't want, from your computer to the network or internet and back.
Do you need to know your MAC address? Most of the time...no. If you connect from inside a secured network, behind a corporate firewall or content filter, then the answer may be yes. Truth is, just as the MAC address allows your content to travel, it allows for some of that content to be monitored and tracked to your computer.
Chances are that if you work for a middle to large company or attend a school, your internet activity is being monitored. WHAT?! But isn't this a violation of my Civil Rights as an American Citizen? No offense to those from other countries, but I am American after all and I have no knowledge of your civil rights…or lack thereof.
Your rights are not being violated...usually. Courts have ruled time and again that the internet connection provided by a company or school is their property. They have responsibility to protect it and their patrons. Most businesses and institutions require that you sign an "Acceptable Use Policy" with stipulation on the use or abuse of the computer network.
In the next installment I will show you how to get your MAC address.
