Def. proxy server : Where a high level of security of required, a proxy Web server may be used to provide a gateway between a local area network and the Internet. The local network is protected by firewall software installed on the proxy server.
If you do a lot of surfing on the internet, chances are you've run into websites that were less than "trustworthy". Spammy sites that you wish had no information about you or your machine. Unfortunately, when you went to said site, they knew what your IP address is, where you live based on that IP address, and a whole slew of other information that can be extrapolated from a simple IP address. By using a proxy, you can avoid that. Proxies provide you with another level of security and safety on the internet. They can also be useful if you have been unjustly "IP Banned" from a website. For example, let's say you have a friend or relative that was a member of a forum that you also belonged to, and they were being a little more than rude on that forum, AND it just so happened they were on your computer at the time. It's possible, and even likely that the forum administrator would IP Ban you. Not due to your conduct, but someone else's. So, a simple solution to this would be to access that forum using a proxy.
Proxies also provide a level of anonymity that would be appreciated by anyone that is concerned about websites gathering too much information about you and your surfing habits. If you visit a website from a different IP each time, it would make it very difficult for them to get a handle on your surfing habits, or even who you were.
There is more than one type of proxy, and more than one level of anonymity. Here are the two primary types that this site addresses:
How can we help? Well, by being a registered member you will have access to our proxy lists. The proxy lists are updated at least every other day, and include HTTP, HTTPS, Sock4, Sock4a and Sock5 open proxies. The proxies are checked to ensure they are working and are posted with the date and time of the check. Open proxies often do not stay open for long, so the longer the time frame between the check and the time you use them - the greater the chance they will not work. So, use them while they're fresh and steamy!
