How a Proxy Work?
The working principle of a proxy is simple if you aren’t going deep into the technicalities involved. As I stated in the definition, a proxy is a server that acts as a gateway between you and the Internet. Why do we need them in the first place? While there are many reasons, the major ones can be summed up to data security.
When you are not using a proxy, requests you send to websites go to the websites directly. However, when you are making use of a proxy, the situation is different. When you send a request, it goes to the proxy server first which then modifies it (if it has to like substituting your real IP Address with another) then sends the request to the website on your behave. The response will be sent to the proxy and in turn, it sends the response back to you.
With this setup and the mode of operation of proxies, your computer can be completely shielded and hidden from the website you are accessing since your computer is not the one sending the request to it.
Proxies allow you to access the Internet from locations you have not visited before and access their local data. While it has many benefits, make no mistake about it – it also has its own shortcomings. Since proxy servers can access the information sent through them, they can, in turn, alter the data and in some cases, become the mode in which Internet censorship is achieved.
Common proxy servers
Proxies have types, depending on the mode of classification. The criteria can be level of anonymity, the number of people using the proxy, Internet protocol type, and IP source. You need to know the types of proxies available so that when trying to make a purchase, you know what you need and what you are about to purchase. Let take a look at the types of proxies based on the different criteria for classification.
Public Proxies are the type of proxies that assigned many people to a single IP Address. This means that many users sometimes, hundreds of users make use of the same IP Address.
This means that if one of the users spam a particular website with it and it gets blacklisted, all the users of that blacklisted IP Address will be affected. They are mostly provided by the free proxy provider and I would advise against using them.
Semi-dedicated Proxy is also known as a shared proxy, just like Public Proxies. the only difference is that only a few numbers of people are assigned to an IP Address. The number is usually 3 per IP and as such, it is better to Public Proxies that will allow hundreds of users.
Private Proxies are also known as Dedicated Proxies. A private proxy is named private because it is assigned only to a single user and only that person can use it – except he shares his authentication details. They are the best type of proxy. However, they are expensive. Unlike in Semi-Dedicated Proxies that the cost is shared among the users, for Private Proxies, only you bear the cost.
A datacenter Proxy is a type of proxy that assigns IPs provided by datacenter to its client. They are more susceptible to detection and subsequent block as they are more associated with spam and generating them is easier. Providers of these types of proxies provide them with unlimited bandwidth and they are generally cheaper.
Residential Proxies are the types of proxies that route client requests through real Internet-enabled devices in people’s homes. Because they make use of the IP Addresses of these devices, they are usually difficult to detect, and as such, the cases of blocks are reduced. They are expensive and usually come with limited bandwidth.
Mobile Proxies are the most expensive of the three types of proxies when classified based on IP addresses used. The IP Addresses used are that of mobile devices and as such, they are percent for use when you need to emulate sending requests from mobile devices.
They are, however, the most expensive and do not get blocked because of the way Mobile Network Operators (MNOs) the ISP of the devices assign IP – IP Addresses are dynamically assigned and changed after a while.
An HTTPS Proxy is built on the client and server communication model. The working principle is simple – the client computer sends a request to the server and the server process the request and sends back a response. HTTP Proxies are the most common types of proxies in use today and most proxy services provide them. As an Internet user, most of the links you use are HTTPS. There is a variant to this which is the HTTP.
While HTTPS is the most common type of proxies, SOCKS is the default type of Internet protocol. It is basic and establishes a TCP connection with another server on the client’s behalf. The connection established is used for routing traffic between client and server.
So, all socks proxies are high anonymity Proxies, No need to worry your IP leak when you using a socks proxy.
