In the daily life of Internet, as a senior netizen, we should have some understanding of the concept of server. So, has everyone heard about proxy servers? Proxy IP service is implemented by proxy server.
1. Proxy server is a relay station for network information.
Generally speaking, when a browser is used to connect directly to another Internet site to obtain network information, a request is sent in response, and the information is sent back. The proxy server is the server between browsers and Web servers, after using a proxy server, the browser will send the request to the proxy server, rather than directly to the Web server for Web pages, 2, request signal is sent to a proxy server, proxy server browser will receive the needed information, and then sent to your browser.
In addition, most of the proxy server has the ability to buffer, as from a local memory storage new access packets, if a browser requests data is the latest in its local memory, and is the latest, so it won't to extract data from the Web server, but the data in memory directly sent to the user's browser. This greatly improves browsing speed and efficiency.
2. The proxy server can not only improve browsing speed and efficiency, but also realize network security filtering and traffic control (reduce Internet usage).
Therefore, it is not only a network firewall technology, but also can solve the problem of IP address shortage caused by multiple units connected to the Internet.
IP switching software is such an intermediary, providing users with different IP addresses to meet the various needs of each user. Users can choose the most suitable IP address, even if you want to use the northern netcom in the south with one click, in the north, you want the southern telecommunications industry. Ignoring geographical differences is only the most basic basis for changing IP, for example, changing IP software for game studios or online marketers, choose the most appropriate IP address, hide their IP address, use the new IP to access the web or conduct operations, etc.
Maybe when we surf the Internet at ordinary times, there will be little need to change IP. However, with the increase of Internet security awareness, IP switching has also become a new way of Internet security, because it can hide our real IP address.
If you need multiple different proxy IP, we recommend using RoxLabs proxy：https://www.roxlabs.io/, including global Residential proxies, with complimentary 500MB experience package for a limited time.
