![如何查找 Google IP 号码的位置:例如 209.85.143.94](https://linux22.com/image/591758/%E5%A6%82%E4%BD%95%E6%9F%A5%E6%89%BE%20Google%20IP%20%E5%8F%B7%E7%A0%81%E7%9A%84%E4%BD%8D%E7%BD%AE%EF%BC%9A%E4%BE%8B%E5%A6%82%20209.85.143.94.png)
我正在构建 DNS 服务,我需要找出查询我的 DNS 服务器的位置。显然,任何使用 Google 公共 DNS(如 8.8.8.8)的人都来自 Google /17 网络,如果我进行 geoip 查找,它会解析为美国,但服务器位于爱尔兰。
我是否真的需要对每个 IP 运行跟踪路由来查明它有多远?
此外,bgp 报告它是 /23 子网,但是我不知道如何获取最新的信息。 http://bgp.he.net/ip/209.85.143.94
