Before developing IPinfo, Xiaoz has been constantly searching for free and useful IP query interfaces. Currently, IPinfo is almost completed and the collected IP query interfaces have been organized and shared, hoping to be helpful for developers.

CZ88 IP

The official website of CZ88 http://www.cz88.net/ provides IP database downloads, which can be used as an offline version. However, Xiaoz couldn't find a suitable online query interface, so he developed an online IP query interface using the IP database provided by CZ88.

• Interface URL: https://api.ttt.sh/ip/qqwry/
• Documentation: https://doc.xiaoz.org/#/api/ip-query
• Frequency limit: 10 minutes/300 times

Taobao IP Address Database

This query interface is provided by Taobao and has been online for a long time, stable and reliable.

• Interface URL: /service/getIpInfo.php?ip=
• Interface instructions: http://ip.taobao.com/instructions.html
• Frequency limit: The access frequency of each user needs to be less than 1qps

IPIP

This interface is provided by ipip.net, which is currently the most accurate IP query interface in China. However, the commercial version is too expensive, and here is the free version interface provided.

• Interface URL: http://freeapi.ipip.net/118.28.8.8
• Interface documentation: api.html
• Frequency limit: 1000 times per day

IP.SB

The data of this query interface comes from MaxMind's commercial version database, and the query accuracy for foreign IPs is relatively high. The author also provides a picture bed interface sm.ms, which I believe you have heard of.

• Interface URL: https://api.ip.sb/ip
• Interface documentation: https://ip.sb/
• Frequency limit: Unknown

Summary

The above are some free database query interfaces collected and organized by Xiaoz. You are welcome to leave comments to supplement.
