What is IP Geolocation Lookup?

Analyzing access logs or tracing abnormal traffic requires knowing where an IP belongs and which ISP serves it. Based on the offline ip2region database, this tool queries locally without calling any third-party API — no rate limits and no leaked query behavior. Batch queries of IPv4 addresses are supported.

How to Use

  1. Enter IP addresses (batch supported, one per line)
  2. View the location and ISP of each

FAQ

How accurate are the results?
ip2region resolves domestic IPs to province/city plus ISP, and overseas IPs to country; the database can lag slightly behind address-block reallocations.
Why is there no district- or street-level location?
IP geolocation is essentially address-block allocation records — reliable street-level data does not exist, and services claiming "precise positioning" are not trustworthy.
