Can't handle high stash IP detection? Teach you how to use Request header to find out the disguise vulnerability.
Now a lot of platforms have learned the hard way that ordinary proxy IPs are blocked just after they are connected. The guys are asking:How exactly do you determine if a proxy IP is a true high stash?Today we will teach you to see the tricky hidden in the Request header and dismantle the testing doorway with real examples from ipipgo.
Browser Fingerprinting Now: These Fields Will Betray You
Detection tools love to keep an eye onX-Forwarded-Forrespond in singingViaThese two fields. Anyone who has used a regular proxy knows that the transit server address is often exposed here. But when using ipipgo's high stash of residential IPs, remember to look at these two places to see if theCompletely blank., not even a hint of a proxy server.
To cite a real-life rollover case: a user accessed the detection site with another proxy and found that the header information was hiding theProxy-Connection: keep-aliveThis kind of fatal field is recognized on the spot. After switching to ipipgo's dynamic residential IP, the entire Request header is clean as a native device, which is what a true high stash should look like.
The devil is in the details: six must-check hidden parameters
Got one for you.checklist, which is more visualized in a table:
| parameter name | normal state | abnormal behavior |
|---|---|---|
| Accept-Encoding | Includes gzip, deflate | The br compression format appears |
| User-Agent | Matching browser version | with the words python/requests |
| Connection | keep-alive | Close or missing |
| Upgrade-Insecure-Requests | The value is 1 | Missing or abnormal values |
| Sec-Fetch Series Parameters | Complete with 3 fields | Missing any one |
| Client Port Number | high level random port (HLP) | Fixed use of 80/443 |
The last time I helped a client troubleshoot a problem, I found that a testing platform would compare theTCP timestamprespond in singingHTTP header timestampThe difference. With ipipgo's static residential IPs, these two times are perfectly synchronized, but some server room proxies can be off by minutes and show up straight away.
Real-world testing in three parts: don't be fooled by fake high anonymity
Recommended to verify with this combo:
1. Start withBrowser Trace Free ModeDirectly visit the test site and take a screenshot to save the original header information
2. Hang the ipipgo proxy and visit the same website, use developer tools to compare the differences
3. FocusHeader orderrespond in singingcase sensitive formatMany inspection systems check these details.
Here's a cold one: certain platforms checkSSL Handshake FingerprintingThe reason why ipipgo's residential IPs are hard to detect is that with real home broadband, the TLS fingerprint is identical to that of a regular user, unlike the server room proxies that carry obvious server characteristics.
QA session: high-frequency problems solved one by one
Q: Detection tools show that anonymity 100% is safe?
A: Don't believe it! Some tools only check basic fields. It depends on whether there is support for detecting advanced features such as JA3 fingerprints, Canvas rendering, etc. This is an area where ipipgo's residential IP has a natural advantage.
Q: Why does the access speed slow down after using a proxy?
A: Maybe the protocol is not selected correctly. Like ipipgo support socks5/http full protocol, according to the business scenario to switch the type of protocol, the speed can be improved 40% or more.
Q: Will I be blocked if I use the same proxy IP repeatedly?
A: Look at the IP type. With dynamic residential IPs automatically changing IPs every time you connect, like ipipgo's rotating pool has 90 million + resources that simply can't be used up.
The last thing I'd like to say is that the quality of the resources is the quality of the high stash of agents. Those who claim to be technically invincible small workshop, resource pool on a few room servers, head information disguised again, people platform directly seal the entire ASN number. ipipgo can do really high stash, relying on more than 240 countries around the world, real residential IP, which is the hard power.
