Why Do You Need a Reliable Proxy Server Address?

In the age of the internet, proxy servers have transformed from a technical term into essential tools for our daily online activities, especially for cross-border users. So, what exactly is a proxy server ?

In simple terms, a proxy server is an intermediary between you and the internet. When you access a website through a proxy, your request first goes to the proxy server, which then retrieves the data and sends it back to you.

This setup has several advantages: it can enhance browsing speed (as proxies may cache data), bypass geographical restrictions (accessing blocked websites), and conceal your real IP address (for privacy protection), among others. If you are conducting market research, understanding the competitive landscape, or analyzing different versions of websites in various regions, a proxy server can be incredibly helpful.

Mobile Proxy (Phone/Tablet) Techniques for Finding Proxies

The demand for proxy settings on mobile devices is rapidly increasing—according to Statista data, global mobile proxy usage has grown by 230% over the past three years. How can you find suitable proxies on your mobile device? Here are some practical experiences:

Official App Stores

Searching for “proxy” in app stores will yield a variety of applications, but not all are reliable. Some recommended apps include ProxyDroid (Android) and Shadowrocket (iOS). These apps not only provide proxy lists but also offer one-click connection features. Users can preview reviews before downloading to avoid poor user experiences.

Mobile Browsers

For example, the “speed up web pages” feature in UC Browser is directly implemented through proxy servers, and you can usually find related options in 【Settings】 - 【Advanced】. Opera browser also directly integrates proxy capabilities for enhanced browsing.

However, it’s important to note that different operating systems have different proxy configuration methods:

• Android: Long press the connected WiFi network → Modify network → Advanced options → Manual proxy settings
• iOS: Settings → WiFi → Tap the info icon next to the connected WiFi → HTTP Proxy select Manual

Mobile internet requires specific configurations. I generally use APN (Access Point Name) modification methods: Settings → Mobile Network → Access Point Names → Create new APN, then fill in the proxy field with the address.

Note:

• Different service providers may limit this functionality.

• Public WiFi proxy connections may be throttled; it’s recommended to enable HTTPS connections when using proxies on mobile devices.

How to Test and Select Quality Proxy Addresses

Finding a proxy address is just the first step; determining its usability and security is crucial. Below is a practical “three-step method” for selecting proxies:

Step 1: Basic Usability Testing

Open the command prompt (CMD) and enter:

“ping proxy IP address”

Check the response time; if it exceeds 300ms, I would label it as “low speed”. Then use a browser to visit https://www.whatismyip.com/ to confirm that the displayed IP has indeed changed.

Step 2: Anonymous Level Check

Visit a site like https://www.whoer.net/ for anonymous level checks, and observe the returned information:

• Is the proxy leaking your real IP? (Key point!)

• Is the DNS matching the proxy location?

• Is WebRTC leaking information? (Especially important for mobile devices)

Step 3: Stability Testing

1.Continuously use the proxy to browse multiple sites, paying attention to the following points:

• Is there a frequent need for verification codes? (Could be shared by multiple users)

• Check the loading speed (test with a speed test tool).

• Is there sudden disconnection? (Indicates stability issues)

2.Location selection is also very important. Depending on your needs, choose proxy locations:

• Cross-border e-commerce price comparison: target country’s local IP

• Content access: avoid countries with strict censorship regulations

• Privacy protection: choose countries with robust privacy laws (e.g., Switzerland, Iceland, etc.)

For long-term use, it’s advisable to build your own “proxy library” using Excel to record the response speed, usable time frames, applicable scenarios, etc. This is particularly important for users looking to develop business services using quality proxies.

Common Issues and Solutions When Using Proxy Servers

Issue 1: Slow Internet Speed After Connecting to Proxy

Solution:

• Check the proxy location (long physical distance may increase latency).

• Try different endpoints (some ISPs may limit speed on specific endpoints).

• Switch proxy agreements (HTTP is generally slower than SOCKS5, but more secure).

Issue 2: Unable to Access Certain Websites

Possible reasons:

• Proxy IP is blocked by the website (commonly seen in social media).

• Proxy server DNS settings issues.

• The website detects the proxy’s characteristics.

You can try switching to multiple proxies or test “residential proxies” (which are harder to detect).

Issue 3: Frequent Disconnections with Mobile Proxies

Optimization suggestions:

• Enable “keep alive” features (if available).

• Use TCP instead of UDP proxies (more stable).

• Avoid using other VPN software simultaneously.

Proxy servers play a significant role in our work and life, but account security must also be prioritized.

For example: Never log into sensitive accounts through unverified proxies, and ensure that the proxy connection is encrypted (the address bar should show a small lock icon), and regularly update proxy passwords.**

By following these practices, you can use proxies to enhance your online presence while ensuring greater choice and security. At the same time, remember that proxies are not infallible; they require proper usage, especially in certain regulatory environments.
