For many people, their Internet service is something that happens as though by magic, but if you are curious about learning more about how your computer gets online and communicates with other machines, you are going to find that you need to think about your IP address. The term IP address is one that comes up with regular frequency when you are thinking about computers and networking and even if you know where to find it, you might not be able to explain what it means or what it does. When you are thinking about learning more about networking and when you want some simple answers as to what an IP address is and what it does, there are some things that you need to keep in mind.

In the first place, remember that the term itself is short for “Internet Protocol.” This is a label that has been applied to allow you to connect to a wider network, and if you are on the Internet, you are using an IP address to get there. Remember, though, that you are looking at something that has several functions. For instance, websites have IP addresses too; from your computer’s point of view, they are both a pathway as well as a location. When you are thinking about the way your computer interacts on the network, remember that it should act as your passport. If you are not getting an IP address, you are not going to be getting online at all. Your IP address is something that is granted to you by your Internet service provider, or your ISP. In many cases, you will be able to simply plug your computer into the wall or into your cable modem, depending on what your service consists of, and you will be able to get online right away. In many cases, you will first need to deal with authenticating yourself to your ISP, and you need to verify that you have service with them, but it usually takes very little time at all. With a greater interest in convenience and speed, there are companies which are deliberately working for plug and play Internet, where you can plug your computer in and simply start surfing as you please. This can make a huge difference to the way that you connect.

Privacy: it doesn’t seem like we have much of it these days. Nearly everything we do these days is being watched. This new surveillance is manifested in many aspects of life. A person just walking down the street could be caught on tape from a store’s outdoor security camera. A driver who runs a red light could be caught on a security camera embedded in the light and sent a nice little ticket and directions on how to pay the fee. Students in school and in college are watched the most closely. In today’s cut throat world, students will do anything that they can to put themselves ahead of the pack, and that includes an unfair advantage by cheating. Some universities with large, lecture style rooms survey test takers with hidden video cameras to try and catch cheaters and give everyone a level playing field. Some on the more paranoid spectrum think the government watches everything we do, and records it all to be used against us later for criminal implications.

This is far from accurate though. While the government certainly does, and this is no secret, record things about the American people, it is certainly only for our safety. Ever since the 9/11 bombings, our country has stepped up security three-fold. This is most noticeable in the airports; the conduit for the brutal attacks. Where you used to go through security with pretty much just a visual check and a quick metal detector, you now spend quite a bit of time. It is not uncommon to see a person having to take off coat, shoes, and belt to be searched and patted down, to make sure they are not a threat. To most though, this is just an annoyance and means they have to wake up even earlier for their flight lest they miss it due to a convoluted security check.
