IP位址查詢
查詢任意IP位址的地理位置、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.
什麼是IP位址查詢？
IP地理定位使用公開註冊資訊（ARIN、RIPE等）和ISP資料，將一個IP對應到大致的實體位置。精度各不相同：通常可精確到城市級別，對於行動IP或VPN，誤差有時可達數百公里。這對於日誌分析、詐騙偵測、內容的地理分發以及CDN除錯都很有用。
常見使用場景
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.
