使用 CNAME 时更改 IP

我想将 96.7.41.139 设置为 download.microsoft.com 的 IP 地址，我查看了这篇文章： https://serverfault.com/questions/452268/hosts-file-ignored-how-to-troubleshoot 并按如下所示设置主机。

96.7.41.139 main.dl.ms.akadns.net
96.7.41.139 a767.dscms.akamai.net
96.7.41.139 download.microsoft.com.nsatc.net
96.7.41.139 download.microsoft.com.edgesuite.net
96.7.41.139 download.microsoft.com

但没有成功。结果如下。我该怎么办？

C:\Users\admin>nslookup download.microsoft.com

答案1

由于缺乏回复，我无法发表评论。不过，补充一下用户 Xyon 的回答，您可以尝试 IPCONFIG /FLUSHDNS 来清除缓存中已有的 IP 地址映射，而不是重新启动。您可能需要执行几次才能清除缓存。

希望这可以帮助。
