>>Proxy servers:-
Its allow for
you to configure your browser to route your browser traffic through that
machine, which then makes a request for a page on your behalf, and then sends
you the results. These are usually used at no cost to the user. Since they are
accessible to the public these are often quite slow. Please see instructions
for using a proxy server. 
There are a variety of types of these proxy servers:
* Transparent Proxy - This type of proxy server identifies itself as a proxy
server and also makes the original IP address available through the http
headers. These are generally used for their ability to cache websites and do
not effectively provide any anonymity to those who use them. However, the use
of a transparent proxy will get you around simple IP bans. They are transparent
in the terms that your IP address is exposed, not transparent in the terms that
you do not know that you are using it (your system is not specifically
configured to use it.) This type of proxy server does not hide your IP address.
* Anonymous Proxy - This type of proxy server identifies itself as a proxy
server, but does not make the original IP address available. This type of proxy
server is detectable, but provides reasonable anonymity for most users. This
type of proxy server will hide your IP address.
* Distorting Proxy - This type of proxy server identifies itself as a proxy
server, but make an incorrect original IP address available through the http
headers. This type of proxy server will hide your IP address.
* High Anonymity Proxy - This type of proxy server does not identify itself as
a proxy server and does not make available the original IP address. This type
of proxy server will hide your IP address.
>>Proxy browser:-

barrier between your internal network and the Internet, keeping others on the

your internal network.........and your browser is become like
