Imagine the following situation: You have a local network in which several computers are connected to each other. One of them also has a telephone connection to the Internet, either its own or through an access provider.

In this way only that computer could have access to the Internet. Obviously, it would be desirable for all other computers on the local network to be able to access the Internet using that single connection.

The traditional solution consisted of using a device called a router (router) dedicated exclusively to this task and which was responsible for transmitting information from one network to another. This is a very expensive solution and in the case of small networks the expense is not justified.

Today there is a simpler possibility that consists of using a proxy, which is a program that acts as a gateway between networks, in the case that concerns us between the local network and the Internet. Every time one of the computers on the network wants to access the Internet, it makes this request to the proxy. The proxy uses the only existing connection to send and receive information from the Internet to the requesting computer. If you are finding proxy services then there are many Proxies provider companies that provide proxy services like Litport.net, they offers you high-speed IP addresses, you can start working with them

How Does A Proxy Work?

From the point of view of the local network user, the system works as if it actually had direct access to the Internet. The user immediately accesses a web page from his computer or receives his e-mail, without even knowing that the proxy exists. thepirateproxybay.com can be a great option to visit if you want to learn more about proxy.

Actually, when opening a program like Internet Explorer or collecting pending mail, the service request is made to the proxy, not to the Internet server. The proxy is in charge of redirecting these requests to the corresponding machine (the web page server or the mail server) and once the information is received, transmitting it to the computer that requested it.

Advantages Of A Proxy

The advantages offered by using a proxy in a local network are the following:

  • Lower cost: The program and the installation have a much lower price than any router.
  • A single telephone line: You only need a normal telephone line or ISDN
  • Easy installation: The installation uses the devices of the local network itself, thus reducing the configuration of the programs.
  • Security: The proxy also acts as a barrier (firewall) that limits access to the local network from outside.
  • Unique IP address: The IP address is the one that uniquely identifies each machine on the Internet. If a proxy is used, one IP address is enough for the entire local network instead of having one IP for each of the computers.
  • Automatic connection (auto dialing): It is not necessary for the computer acting as a proxy to be permanently connected to the Internet. With this function, every time a user makes a request, the proxy establishes the connection. In the same way, the proxy disconnects it when there is no request, all automatically.
  • Less network traffic: The proxy automatically stores frequently accessed web pages in memory, reducing the amount of information that needs to be retrieved over the Internet.
