    The first thing you have to know about proxy servers, is that in some states and countries, it is illegal to access a proxy IP without express permission from it’s owner. So make sure what you are doing is legal in your country before proceeding.
    There are many different kinds of proxy servers, and even more ways of finding them. Proxies are divided in two main categories.
    Web proxies, which you access through your browser like accessing a normal website, and open or private proxies, which are computers set up in a way to let you transmit data through them. To use an open proxy, or a private proxy, you need their proxy ip and a port number that their owner set up.
    If you got one, but do not know how to use a proxy IP, here are a few guidelines.
    If you only have an IP, without a port number, then try entering the IP into a browser address bar, and see if it takes you to a website where you can enter an address of a website that you want to access through it. If this works, then you have an IP for a web proxy. If it doesn’t, then you are out of luck, because for the other proxy type to work, you also need a proxy port. If you have both, then what you have is usually an open or a private proxy. To make one of these work for your browser, you must enter the proxy IP and port number in your browser options, and then continue browsing as you normally would. A way to see if the proxy is working, is going to a website that tells you your IP address, and if the address you see is the same as your proxy IP, then the proxy is working and you are browsing anonymously.
    There are different levels of anonymity of proxies.

    Transparent proxies
    These proxies identify themselves as proxy servers when connecting to a host, and also leak your real IP address through the http headers, making it possible for the remote host to see who is behind the proxy. These proxies are the least safe of all three types.

    Anonymous proxies
    These type of proxies also identify themselves as a proxy server, but they don’t reveal your IP address to the remote host. So all they know is that somebody is using the proxy, but they do not know who that is.

    High anonymity proxies
    These proxies are the safest of all three types. They send out header information as if it was a normal computer who is connecting to the host. The remote host does not know that you are using a proxy to connect to it, and you are completely safe.
    There are also many risks involved when connecting through a proxy IP. One of them being that those who own the proxy server may log all the data you send through it, and use it for malicious purposes.
    Now you know how to use a proxy ip address, and the risks you take when using one. So please use them carefully, especially if you do not know who you are connecting to.
