Think of a shared proxy as a carpool. You get to your destination, but you’re not the only passenger. Because many users send requests through the same IP, websites on the other end can’t easily tell who’s who. This setup makes shared proxies budget-friendly and widely available, but it also introduces risk.
If one of the users in that “carpool” engages in suspicious activity, the IP address can get flagged or blocked—affecting everyone sharing it. For this reason, shared proxies are often considered entry-level: good for casual browsing, basic scraping, or quick tasks where reliability isn’t mission-critical.

用例
Casual Browsing
A shared proxy can help hide your IP while browsing websites for privacy reasons, without needing the higher cost of a dedicated solution.
Testing Access
When developers need to quickly test how a website looks from a different location or IP, shared proxies provide an inexpensive option.
Lightweight Data Collection
For small-scale web scraping, like pulling a handful of prices from an e-commerce store, shared proxies can do the job without breaking the bank.
最佳实践
Don’t Rely on Them for Sensitive Tasks
If you’re managing multiple social accounts or running high-value automation, shared proxies are risky. Stick to them for lower-stakes activities.
Monitor for IP Blocks
Because others may misuse the same proxy, always keep an eye out for sudden bans, captchas, or throttling. These signs often mean the shared IP has been flagged.
Upgrade When Scale Grows
Start with shared proxies if the budget is tight, but plan to move to private proxies or dedicated proxies as soon as reliability becomes important.
结论
A shared proxy is a cost-effective way to mask your IP address by pooling it with other users. It’s simple and affordable but comes with trade-offs in stability, speed, and trustworthiness.

经常问的问题
Are shared proxies safe to use?
+
They’re generally safe for light, non-critical use, but the risk of bans is higher since multiple people use the same IP.
What’s the difference between shared and private proxies?
+
Shared proxies are used by many users, while private proxies are reserved for a single person or organization, offering more stability and security.
Why are shared proxies cheaper?
+
The cost is divided among multiple users, making them far more affordable than dedicated options.
Can I use shared proxies for social media accounts?
+
It’s possible, but not recommended. Platforms like Instagram or TikTok may quickly block accounts if they detect suspicious activity from the shared IP.
