IP proxy has always been a rigid demand for cross-border business. In addition to playing a huge role in cross-border business, high-quality IP proxy also plays a big role in SEO monitoring, crawler crawling, market research and other fields. However, the quality inspection of IP proxy is a sentence for us to choose high-standard IP proxy. We generally recommend testing or inspection before using IP proxy. So how should we quickly detect the effectiveness and quality of proxy IP?

The following article will introduce you to the proxy IP detection and judgment methods in detail. If you are interested, read on!

1. Testing tools

The most commonly used IP detection tools include Ipapi, Ip2location, whoer.net, and Ipinfo. When you open these tools, your IP address will be automatically parsed, and some noun coefficients will appear. So we first need to understand them.

2. Explanation of test results

Without further ado, I'll use an IP proxy I use myself (from kookeey) to conduct a practical test:

1. whoer.net

This tool is based on the browser to obtain the corresponding information, so the most basic GPS positioning, signal base stations, mobile phone operators, and deeper hardware information are not reflected in whoer.net. It is mainly used for DNS detection and anonymity detection. Its popularity is related to the development of TK.

l IP address : Displays the current Internet access IP address, and can be used to check whether the proxy is effective;

l ISP : Simply put, it refers to domestic operators such as China Unicom, China Mobile, and China Telecom;

l Host name : The host name is the name of the server;

l OS operating system : This is the system of your phone or computer;

l Browser : The browser you use will be displayed.

l DNS : The computer first addresses the DNS server, and then addresses the site itself. The same domain name is assigned different IPs in the DNS of different places. If the DNS in the area where the IP is located is unstable or busy and cannot process the request immediately, it will be automatically resolved to the best DNS node nearby;

l Proxy server : refers to whether a proxy server is used to access the Internet;

l Anonymizer anonymous server : it can hide the IP address without saving IP connection data;

l Blacklist : It means that the proxy IP is blacklisted in the database of this detection website, such as the IP sending spam or illegal behavior.

2. Ipinfo

The main business is IP geolocation query API and IP proxy monitoring.

l ASN : Autonomous System, which implements IP to ASN mapping and ASN lookup;

l company : the company or organization that owns the IP address, usually classified as ISP, enterprise or hosting;

l private : Detects various methods used to mask the user's real IP address;

vpn : virtual network; proxy: proxy; tor: Tor (a type of proxy); relay: relay use; service: service

Abuse : Contact information of the abused IP address to help research and track down abusers or thieves.

The above are the analytical terms that appear in almost all proxy detection tools. The four tools mentioned above basically detect this information.

3. IP type determination

Native IP: It means that the DNS and IP address are from the same country, which can be considered native. However, there are special cases, such as some countries in Southeast Asia and Europe, where the DNS will be resolved to a nearby country. The ISP proxy I tested is purely native, and I have never encountered any problems using it at the business level.

Dual ISP: The commonly mentioned dual ISP refers to the type attributes of ASN and Company found in the query. Some so-called residential IPs have an ASN that belongs to the operator, so they are ISPs, but the company is not. This is a single ISP, and the real residential IP, whether it is ASN or the operating company, should be a local operator. For example, the IP of kookeey that I detected is a dual ISP. In theory, such an IP is more stable.

4. Final Thoughts

The above is the detection method and detailed introduction of IP proxy. If you are interested, you can test it yourself. It is recommended that before purchasing and using IP proxy, you can choose an IP that can be tested for free to conduct business testing. After all, there is no absolutely excellent proxy, only the proxy that suits you.
