Why can high-storage proxy IP "stealth" anti-crawler?
Many people use proxy IP to fight against anti-crawlers, always encountered IP was blocked in seconds. The core problem is that the proxy is not transparent enough - the server can easily recognize that it is proxy traffic. The special thing about high stash proxy IP is that itCompletely hides the client's real information, the proxy feature in the request header is completely erased as if it were directly accessed by a normal user.
Ordinary proxies will expose X-Forwarded-For tags in the request header, while high-stash proxies like ipipgo not only replace the exit IP, but also rewrite all the protocol fields that may expose the identity of the proxy by using multi-layer protocol conversion technology. Measurement data shows that the recognition rate of requests using high-quality high-stash proxies can be reduced to less than 0.3%.
A three-step hands-on approach to breaking through dynamic countercrawl
When encountering an anti-crawl system based on IP behavior analysis, simply changing IPs is no longer enough. Here we share a battle-proven combination:
1. Multiple geographic IP mixing: Select residential IPs for different countries/regions via ipipgo, it is recommended to switch 2-3 IP addresses with a wide span of time zones per request. For example, the first time you use US West Coast IP, next time you switch to Germany IP and then cut to Japan IP.
2. Device Fingerprint Emulation: Modify browser fingerprint parameters such as User-Agent, screen resolution, and so on. Note that every time you switch IP, the fingerprint information should be changed synchronously to avoid the breakage of "New York IP with Chinese browser".
3. Pace control of visits
Mechanized high-frequency access is a minefield that triggers anti-crawling. It is recommended to setRandomized delay mechanism: Generate irregular intervals between 10 and 180 seconds to simulate the rhythm of human operations. It is also important to avoid centralized access at regular time points such as whole time and half time. The situation encountered in an e-commerce price monitoring project is typical: the target website blocks 200+ proxy IPs per hour. after changing to ipipgo high stash proxies, stable collection is realized through the following configuration: Together with the customized browser fingerprinting library, the solution ran continuously for 72 hours without being blocked, maintaining a success rate of over 99.2%. Q: Will highly anonymous proxies definitely not be recognized? Q: What should I do if I encounter human verification? Q: How do I detect if an agent is high stash? Not all agents who advertise a high stash are reliable and it is recommended to focus on them: Taking ipipgo as an example, its residential IP pool covers the global home network environment, and the maximum survival time of each IP is no more than 24 hours, which is a dynamic characteristic particularly suitable for countering anti-crawling strategies based on the analysis of historical IP behavior.Classic case studies of breakthrough validation

Frequently Asked Questions QA
A: There is no 100% unrecognized technology, but high-quality service providers such as ipipgo use real residential IPs with deep hiding technology at the protocol layer to minimize the risk of recognition.
A: At this time you need to reduce the request density of a single IP, it is recommended to turn on ipipgo'sIP cooling function, let the verified IP be silent for 12 hours before using it.
A: Visit a testing site like whatismyipaddress.com to see if the Proxy, etc. logo is exposed in the results. A real quality high stash proxy will show up as a regular home broadband connection.Key Indicators for Choosing a High Stash Agent
