Have you ever heard of proxies? What is a proxy about? When you surf through your cellphone and other online activities. You certainly need a device that is connected to the internet. Can be through a data package, or also wifi. Meanwhile, computers, laptops. or the mobile phone is connected via the internet and then gets access to an IP address (Internet Protocol), the server/router/ISP will then find out which device you are using. Data such as location, type of device, and also user information then the internet knows it.
You must be surprised. That means whatever I access is visible, please. Is there a way to just hide the identity. Of course there is, that's what we will discuss, namely using a proxy. What is a proxy and how does it work and use it?
What is a Proxy?
Proxy Server 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 we use 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 providers like bags, books, shoes, and clothes providers online. However, there are a few things you should know about its function and how it works.
Multiple servers, it can be a group of applications or servers that block common internet services. For example, HTTP proxies intercept web access while SMTP proxies intercept email access. Proxy servers use a network addressing scheme to serve an organization's single IP address to the internet. After that, all user requests are sent to the internet and the response is returned to the user.
In addition to limiting access from outside, this mechanism can prevent users from reaching certain websites. Not only that, a proxy server can also be used as a firewall component and cache web pages. So, every time a user accesses a URL, a temporary copy will be stored locally so that the proxy website can be accessed more quickly when we reopen it.
Ways of working
Every computer connected to the internet must need an IP address. As we know, that IP Address is like our home address, IP Address can help to know which data will be sent.
If you surf the internet, for example google. You are looking for a specific keyword. You mean giving requests and requests to search engines or in a state of accessing websites. Then he will send requests to the website server, then take a response from the website server and also finally appear in your browser.
Then the server forwards the request, the proxy can also change your IP address so that the website server does not know exactly where you are accessing data. Finally, your data can be encrypted and unreadable during transit, lastly it can block access to certain web pages based on IP addresses such as access to websites that are prohibited by the government.
Benefits and Uses
Well, after you know the meaning and also how it works. Let's discuss the benefits and uses. Here are also the reasons why so many other friends are also maximizing the benefits of proxies.
some reasons users switch to using and maybe you are interested in using it too:
- Some users don't want their identity known: the location and IP address we use, so they hide it.
- Sometimes some schools restrict access to certain websites. Students then work around this so that 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.
- Controlling the internet usage of employees and children
- Save bandwidth and increase speed
- Get access to blocked resources
Proxy Types
Transparent Proxy
This first type will notify the website and send your IP address so that your access request will be processed. Businesses, public libraries, and schools often use transparent proxies to filter content because it is easier to prepare data from the client and server sides.
Anonymous Proxy
This type of time can identify itself as a proxy, but will not forward your IP address to the website. This can help you maintain the security and confidentiality of your data. For example, when the press makes a story about where you live, they will display news that they think is relevant to where you live. But we can minimize this if you use this type.
Distorting Proxy
This type can spoof an IP address when identifying as a proxy. It functions much like an anonymous proxy, but by sending a fake IP address, you can change your access location to different from your real location so that you can access content that has been blocked.
High Anonymity Proxy
This type is different, it periodically changes the IP address they give to the web server making it very difficult to track internet traffic. This type is one of the most anonymous and secure way to access almost any content on the internet.
