What is a pure ip: high anonymity proxy IP identification standards in detail

What does a real - high anonymity proxy look like? Teach you to spot a fake pure IP at a glance...

Recently, Mr. Zhang, who is engaged in data collection, stepped into a pit. He spent a lot of money to buy a "high anonymity proxy", but the target website was blocked just after two days of use. It's like buying a watermelon, you never know if it's sandy or watered down until you cut it open. Let's break it up and talk about it.Highly anonymous proxy IPs must pass these three hurdles::

Level 1: Agreement to act like a real person

Normal proxies are like going to the grocery store in a costume - the X-Forwarded-For field in the HTTP header reveals that you are a proxy. A truly highly anonymous proxy has to doAll-protocol camouflage, modeling browser fingerprints, time zone languages, and SSL handshake characteristics exactly like home broadband. Professional service providers like ipipgo even dynamically adjust the TTL values of TCP handshake packets, knowing the network characteristics of home broadband better than your own mother.

Level 2: IP address should be "accountable"

The difference between a residential IP and a server room IP is like the difference between a neighborhood resident and an express hotel guest. The website risk control system has now learned to check the "account book", the IP segment of the server room, the IP segment of the cloud service provider has long been lying in the blacklist. ipipgo covers 90 million + real family IP, each IP with a serious ISP (broadband operator) "account certificate Each of these IPs comes with a proper ISP's (broadband operator's) "account certificate", so you can't tell if it's a real person or a machine when you're grabbing data.

Level 3: Leave No Digital Footprints

Some proxies appear to be hidden, but actually reveal themselves when they are used. It's like wearing a nightclothes but spraying cologne - DNS resolution records reveal the real location, visit intervals as regular as robots, web page loading time is too stable, all these details will trigger the website alarm. A real high stash of proxies should be like a loach, randomly changing exit nodes every time it connects, and accessing at a pace with a bit of manual operation "clumsiness".

Self-inspection checklist for avoiding pitfalls (take a notebook)

1. UseBrowser Leak Detection SitesCheck WebRTC
2. Look at the request header to see if there is a proxy logo such as X-Forwarded-For.
3. Check whether the IP's ASN belongs to a regular broadband operator.
4. Visit the same web page continuously to see if the CAPTCHA is triggered.
5. Observe for sudden spikes in the number of TCP connections

Frequently Asked Questions on Crime Solving Time

Q: How do I measure the anonymity level of an agent?
A: It is recommended to use a multi-layer detection method, first to see if the request header is clean, then to check the DNS resolution records, and finally to verify with the actual anti-climbing strategy of the target website. ipipgo offersReal-time anonymity detection interface, the call will get a detailed analysis report.

Q: Why is pure IP so valuable?
A: Residential IP resources are limited and maintenance costs are high. To ensure that each IP is "clean", real-time monitoring of the frequency of use, regular rotation of contaminated IP, these invisible investment accounted for more than 60% of the cost of service providers.

Q: How to choose between dynamic and static IP?
A: the need for long-term login selection of static residential IP (such as raising the number), short-term intensive collection with dynamic rotation. ipipgo support for two modessecond switchThe background can set the IP survival time from 5 minutes to 30 days freely adjustable.

In the final analysis, choose a high stash of agents like looking for a date, can not just listen to the matchmaker blow, have to be on their own hand test. Those who dare to open the API test interface service providers (such as ipipgo trial channel), is really on their own technology has the bottom line.
