As internet access expands, network administrators face a series of issues including IP address shortages, user access billing, and internal network security. Overseas proxy servers are one effective method to address these problems. This is because foreign proxy servers offer various functionalities that serve numerous purposes in daily networking, specifically in the following aspects:

1. Shared network functionality: Overseas proxy service providers commonly offer shared internet access, a usage that many people unknowingly engage in. For instance, using software such as Sygate, WinGate, ISA, CCProxy, and the built-in network sharing feature in NT systems, enterprises can provide enterprise-level file caching, replication, and address filtering services. Overseas proxy servers allow businesses to make the most of limited bandwidth at LAN exits, resolving many related issues and facilitating internet user management.

2. Access proxy functionality: Overseas proxies can expedite website access speed. In instances of network congestion or interruption, users can access destination websites through proxy servers. Proxy service providers explain that if user A wants to access website C, but encounters network issues on the way from A to C, allowing access to public data is possible. Assuming B is the proxy server, A can go through B to reach C. Another type of proxy server backs up a considerable number of cache files. If the data being accessed is already in the proxy server's cache files, it can be directly retrieved without connecting to the remote web server, thus speeding up access.

3. Attack prevention functionality: By utilizing overseas proxy servers, you can protect your real address information and your IP while accessing websites securely. Overseas proxy service providers explain that by analyzing specified IP addresses, a network user's current location can be identified. These are the main functionalities of overseas proxy servers. Additionally, they also include features such as data scraping, safeguarding secure access identities, and enhancing speed.
