Lots of Internet users choose to change IP in a bid to hide from what the Web community would call “sniffers.” Sniffers are an Internet user's term of referring to the hacker tools that are used to pry out information and personal data from an online surfer. Hackers and other learned people use the sniffers to find out your IP address, your web browsing history, cookies, your computer system, and even your files. Knowing there are such things that are used to spy on your Internet habits, how could you not worry about your privacy whenever you surf online?

You will be surprised at just how much information about you is made available to other people, all from just your Web browsing habits. Companies and online business also employ such tactics in order to obtain information for their market research and customer database. There may be no bad intention in this case, but the thought of our personal information becoming open to the Web community is enough to make us worry about our security online.

Whenever we go online, our every action and every hit on the Enter key gets logged into the Web. For example, if we are searching for herbal medicine online, they keyword we typed in, our IP address, the time, our location, and other information will be recorded. If the site we stumble upon in search of the herbal medicine is conducting online surveys for their products, our information will also get to them with the help of the sniffers.

When this happens, you will start getting spam emails and pop-ups that will advertise different products and services. A more irritating scenario would be if they get a hold of your phone number and try to contact you into buying their products and services. The worst case scenario would be if you start getting junk mail at your home from other companies of the same nature. It is rather annoying knowing all this came from just surfing online for an herbal medicine.

An even worse case scenario would be if it is a malicious hacker that's targeting you. This is perhaps the worst kind of predicament you will be in. A hacker sniffing out your IP address, your location, and your information could mean big trouble. This big trouble can equate to identity theft or the abusive use of your profile and your accounts, which can really spell out a huge loss for you.

This is why it has become such a big deal for knowledgeable internet users to changing IP. The basic idea is to protect ourselves from the Web and from the hackers. Our personal information should remain private and this cannot be possible if the online community can sniff out your IP address. When your real IP is out you can be tracked easily and hackers can gain entry into your computer system fast. Once they are in, your files and programs are at their mercy, and you'll end up with your accounts touched and your computer crashed. The best solution to hide from the sniffers and the Web trackers is to change IP.
