Proxies, Types and How They Work

When doing online activities, the device must be connected to the internet network. As soon as your computer, laptop or mobile device is connected and gets access to an IP (Internet Protocol) address, the server/router/ISP will get information about the device you are using. Some of them are location, device type, even user information.

Of course this becomes an uncomfortable thing if the original identity that we use is known by other people or the websites we visit. Is there a way to hide it?

Of course there is, one of them is to use a proxy. What is a Proxy and how do I use it? We will review it in this article. However, before that, let’s talk a little about the internet protocol.

Origin of Internet Protocol (IP) Addresses

You may not know that every time you access a website, the internet will automatically give the device an ‘address’. This address we know as Internet Protocol (IP).

IP is used to identify where the server should send website content. So, other devices/servers know where information (email, website data, photos, etc.) is sent back to the device/computer you are using.

The address used by your device is a public IP address that all devices must have to access online.

Without this address, the device cannot be used for online activities and other online activities cannot reach the device you are using. This is how we connect with the world that we don’t even get out of our work chair.

However, there are a few realities regarding public IPs that do bother some people:

  • IP can be used to block user access.
  • IP can be used to identify our names through the internet network around the world, even the information obtained can be more than that.
  • If the IP is used by someone who has the ability to break into (hackers) it can be a serious threat.

What are Proxies?

Proxy is a system that allows us to be able to access the internet network using a different IP from the one received by the device. This system uses a proxy server to work. While the proxy server itself is a device or computer that is used to provide proxy services.

So, you continue to use the internet network that is used now and connect to the proxy server. You can use several free proxy server providers that are already widely offered on the internet.

It’s easy to find proxy server providers, such as bags, books, shoes, and clothes providers online. However, there are a few things you should know about proxies and how they work.

Benefits of Using Proxies?

There are several reasons you need to know why you should use a proxy as a bridge to access the internet network. One of them is because access is blocked so you can’t open sites from certain countries or IP addresses.

Below are some reasons why users switch to using proxies and you might be interested in using them too:

  • Some users don’t want their identity known: location and IP address used, so they hide it by using a proxy.
  • Sometimes some schools restrict access to certain websites. Proxies are used by students to work around this so they can access blocked websites.
  • Users who go abroad and block access to your home or home country.
  • Your office or home internet service provider blocks access to social media or other sites.

Types of Proxies

Although proxies help us in accessing websites, it turns out that not all proxies work the same way. Proxies can be categorized into four types, namely:

a. Transparent Proxy

This type provides information to the website that the connection uses a proxy server and will still pass on your IP information.

b. Anonymous Proxy

This type will identify itself as a proxy, but not send/forward the real IP address you are using.

c. Distorting Proxy

This type of proxy will provide a different IP address than the one you are using, but still identify itself as a proxy server.

d. High Anonymity Proxy

This last type is a type of proxy that hides the identity of the proxy server and the IP address used by the user. The website will only see a random IP address connecting to it, not your own.

Proxy Function

Based on some of the reviews we discussed earlier, there are several proxy functions in general, including:

a. Improve User Security

The proxy server has a function to prevent websites from recording your real IP address because what the website detects is the IP address of the proxy server. So using a proxy server is the same as making an anonymous online connection.

This is to anticipate your IP address is known by many people. As discussed earlier, an IP address can provide information about your country and city of origin.

b. Traffic Monitoring

Proxies can be used to monitor internet users accessing anything. This is good for implementing in educational institutions as well as companies, to monitor internet abuse. One way is to use Squid.

c. Accessing Blocked Networks or Websites

Sometimes some content is hidden by the owner or geo-restricted, mostly due to network and copyright regulations. However, the proxy server hides your site address and then uses the proxy server address.

How Do Proxies Work?

The proxy server is in charge of forwarding your connection to the website address you want to open. What does it mean?

Normally, when you type in a website address, your Internet Service Provider (ISP) makes a request to you to connect it to the destination address.

However, the conditions are different when using a proxy server. The connection you use will first connect to the proxy server. Only then will the proxy server forward your request to the destination address. This method makes the real IP address that you use cannot be detected by the website and what you use is the IP address of the proxy server.
