A proxy server is a tool for ensuring anonymity, bypassing bans, improving security, speeding up page loading, and saving traffic. It performs an intermediate role between the user and the requested resource, redirecting network traffic through itself. In this article we will tell you about different types of proxy servers and their features. You can buy such proxies from proxys.io.
Paid and free proxies
Paid ones offer stable operation, high speed, a wide range of server locations. Provide better protection of privacy and data security compared to free ones.
Free proxies have limitations on speed and available server locations, are less secure due to mass connections to a single IP address. Often created to steal users’ personal data.
Mobile, server, resident proxies
Proxy servers are categorized based on their physical location:
- Mobile proxies are provided by mobile carriers who allocate dynamic IP addresses from their pool to their customers. These addresses change with each new connection to the network, making them difficult to track and identify. Mobile proxies are different in that they offer a wide pool of IP addresses that the user can switch between. Servers are useful for dealing with multi-accounting as they offer a large pool of ip addresses;
- Server-based. These are used in corporate networks. They control and filter Internet access for employees, thus allowing them to restrict access to specific Internet resources to improve staff performance. Also suitable for multi-accounting and bypassing regional restrictions.
- Resident. Based on IP addresses of devices located in home networks or offices. Provide anonymity because their IP addresses are associated with real users.
IPv4 and IPv6 proxies
The IPv4 (Internet Protocol version four) and IPv6 (Internet Protocol version six) protocols define the way devices on the Internet are identified and addressed.
IPv4 proxies use IPv4 addresses consisting of a 32-bit number, such as 192.168.0.1. However, due to the scarcity of IPv4 addresses, there is a need to move to an advanced protocol. Unlike the older version, the fourth will cost more due to the fact that the sixth version is equipped only with large projects, such as Twitter, Facebook, Instagram and others.
IPv6 proxy servers work with IPv6 addresses consisting of a 128-bit number, for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334. This protocol offers a wide range of addresses and provides network scalability and security.
HTTP, HTTPS, SOCKS protocols
HTTP (Hypertext Transfer Protocol) are used to redirect HTTP traffic. They are used for web traffic management and filtering, data caching. In simple words, it is a method that provides a direct connection. It does not hide the data being transferred.
HTTPS (Hypertext Transfer Protocol Secure) proxy servers provide a secure connection using SSL/TLS. Encrypts the data between the client and server, providing security when transmitting sensitive information data such as passwords and banking information.
SOCKS (Socket Secure) universal protocol. Redirects types of network traffic, independent of protocol type or program, including TCP and UDP. Proxy servers running on the SOCKS protocol provide anonymity and access to closed sites and services on the Internet. Mask the real IP address, hide the physical location. Do not allow third parties to track your activities on the Internet.
What to consider when choosing a proxy server
The safety and reliability of proxy servers depend on the provider you choose. Paid proxy servers, especially those that offer a wide range of locations and support various protocols, usually offer stable and secure services.
Speed of operation
Low speed slows down the transfer of information. Creates inconvenience when using internet services. As a rule, paid proxies are hosted on high-quality servers, which, in turn, allows you to maintain a consistently high speed.
Location
If you need to bypass geographical restrictions or simulate access from other countries, choosing a proxy server with the right location will be an important factor.
Summary
It is important to consider the protocols supported by the proxy server. They affect the security and functionality of the Internet experience. If you want to access restricted sites, HTTPS or SOCKS5 proxies will do. For comfortable surfing on the Internet HTTP is suitable. If you want to work with different applications via proxy – SOCKS5.
