IP地址查询
查询任意IP地址的地理位置、ISP和ASN。
如何使用本工具
- 1
Type an IPv4 address (e.g. 8.8.8.8), an IPv6 address, or a domain name (e.g. example.com) into the input field.
- 2
Click Lookup to send the query to our server, which fetches the record from the ipapi.co database.
- 3
Read the returned fields: IP, city, region, country, postal code, latitude, longitude, timezone, organization, and ASN.
- 4
Change the value and click Lookup again to check another address; an invalid or rate-limited request shows an error message instead of results.
什么是IP地址查询？
IP地理定位使用公开注册信息（ARIN、RIPE等）和ISP数据，将一个IP映射到大致的物理位置。精度各不相同：通常可精确到城市级别，对于移动IP或VPN，误差有时可达数百公里。这对于日志分析、欺诈检测、内容的地理分发以及CDN调试都很有用。
常见使用场景
Investigating a suspicious login or order by checking whether the IP in your logs resolves to the country and ISP the user claims.
Debugging a CDN or DNS issue by confirming which network and region a server IP belongs to.
Enriching web analytics or fraud-scoring records with the country, ASN, and organization behind a visitor's address.
Verifying that a VPN or proxy is exiting in the expected country before running a geo-restricted test.
Looking up the ASN and org of an address that is hammering your firewall logs to identify the responsible hosting provider.
Quickly resolving a domain to its hosting location when triaging an abuse report or a downtime alert.
