# 位置与 ISP 信息

我们使用 [MaxMind GeoIP2](https://www.maxmind.com/en/geoip2-databases) 用于确定 IP 位置的数据库。 

要访问具有特定位置的 IP，您无需提供任何额外参数。只需向与所需位置分配的 IP 关联的端口发送请求即可。 

### ISP 提供商和 ASN 检查

我们理解您可能需要验证您的 ISP IP 的网络提供商。某些数据库可能会为 ISP 提供商或 ASN 显示不准确的数据，因为它们通常显示的是原始 IP 地址所有者，而不是当前公布该 IP 的网络。为确保您获得最准确的实时数据，我们建议在中查看您选择的 ISP 提供商和 ASN 数据 [RIPEstat](https://stat.ripe.net/) 数据库中检查 ISP 提供商和 ASN 数据。它反映了该 IP 当前的互联网公告状态。
