High Stash Server: X-Forwarded-For Header Camouflage Analysis

How the hell did this thing hide the IP?

Making a web request is like delivering a courier, where each package is labeled with the sender's address. the X-Forwarded-For header information is the"Handler's records"The common proxy is like a postman who directly stamps a red stamp on your parcel. Ordinary agent is like a stagecoach, directly on your parcel stamped with a red stamp "Zhang San hand", the target server will know at a glance that the agent forwarded. The high stash of agents have to make the recipient think that the courier is sent directly from your home, and even the fingerprints of the postman can not be left.

As a chestnut, when you initiate a request with ipipgo's dynamic residential IP, our server automatically puts theX-Forwarded-For header changed to randomly generated fake addressThe first step is to make sure that the delivery note is reshaped and sealed. The target site to see the chain is this: client IP → proxy server → target server, but the intermediate links of the "handler record" has been completely disrupted reorganization.

Hands-on with XFF camouflage

Here's the point! Remember these three mnemonics in practice:Disorganized, mixed and unmarked. This is done in three steps:

1. Erase the original XFF record when requesting access to the proxy, like erasing old handwriting from a courier note.
2. Generate 3-5 sets of virtual IP addresses, preferably in a mix of different regional formats (e.g., U.S. IP mixed with a Brazilian one)
3. Put the current proxy export IP at the end of the chain, so that the target server can only see the proxy IP

There's a lazy trick to using ipipgo's service - ourIntelligent Routing SystemIt will do all these shuffling operations automatically. All you have to do is add the "xff_shuffle=true" parameter to the API call, and the system will generate the perfect camouflage chain for you like a bartender shaking dice.

Don't step on the three main pits that can lead to a fall.

Seen too many people flip their cars at these places:

• IP format wearout (e.g. generating a fake IP with a non-existent address like 294.168.1.1)
• Chain length anomalies (suddenly there are 20 transit IPs, any fool knows there's a problem)
• Conflicting geographic information (IPs claiming to be from Alaska but carrying Guangdong Telecom's ASN number)

Here's a shout out to ipipgo'sGeographic Fingerprint LibraryOur 90 million residential IPs are labeled with real carriers, and the geographic characteristics are automatically matched when generating the fake chain. It's like matching a fake ID card with a full set of account books, it's impossible to see the cracks.

Practical QA: you're going to want to ask these

Q: Is it useful to change the XFF header with a free proxy?
A: Wake up! Free proxy IP has long been the major sites in a small book, like a wanted man ID card to go to the room, change a fake name is useless. ipipgo's residential IP pool is updated every day 15%, to ensure that every time you use the "clean identity".

Q: How do I test the camouflage effect?
A: Look for "anonymous ratings" on a testing site like whoer.net, focusing onX-Forwarded-For chainsThat column. If it says "Proxy use not detected", that's it. If there are data center IP segments in the chain (e.g. AWS/GCP), change ipipgo's residential IP.

Q: What should I do if I encounter a website that detects XFF headers?
A: You have to sacrifice ipipgo's in this caseprotocol obfuscationFunction. Disguise the request as normal browser behavior, like putting a Jingdong box on a courier package. Combine this with dynamically changing the XFF format to make the detection system think that a different user is operating.

At the end of the day, XFF camouflage is a cat and mouse game. Ordinary proxies are like paper tigers, which can be recognized in two days. ipipgo's power lies in the fact that it uses 90 million real residential IPs as a "shield", and each request is sent from a different home network environment, which, together with its intelligent stack, makes it impossible for target websites to figure out the rules. In order to play this technology, the key is to choose the right weapon.
