The use of online proxy IPs is widespread and the technology is well established. As evidence of this, consider the fact that many domestic broadband operators, such as China Telecom, China Unicom, Netcom, China Mobile, and others, support the use of PPTP or L2TP protocols. Even mobile computers and tablets, such as those running Microsoft Windows, Google Android, Apple iOS, or OS X, have built-in proxy settings that can be used to connect to a proxy server without the need for an IP accelerator client.

The online proxy IP allows users to hide their real IP addresses and protect their privacy and security while browsing the internet. However, there are some drawbacks to consider. The use of an online proxy IP can slow down the network speed due to the need for intermediate forwarding. In addition, free proxy IPs may have security vulnerabilities and the use of shared online proxy IPs can result in slow speed and the possibility of IP expiration, causing difficulty accessing certain websites.

For these reasons, it is recommended to use a paid proxy IP service if you need to protect your privacy and security or require a stable, high-speed IP. Paid proxy IP services offer better security, stability, and speed compared to free or shared online proxy IPs.
