通过命令行工具查找
使用 nslookup 命令
nslookup 是一个用于查询DNS记录的工具，可以很方便地用来查找域名对应的IP地址,在Windows和Linux系统中都可以使用。
Windows系统：
打开命令提示符（CMD）,输入以下命令：
nslookup example.com
example.com 是你要查询的域名，执行后,你会看到类似如下的输出：
Server: dns.example.com Address: 192.168.1.1 Non-authoritative answer: Name: example.com Address: 93.184.216.34
Linux系统：
打开终端,输入同样的命令：
nslookup example.com
使用 dig 命令
dig 是另一个强大的DNS查询工具，它提供了比 nslookup 更详细的信息,在Linux和Unix系统中广泛使用。
在终端中输入以下命令：
dig example.com +short
你会看到类似如下的输出：
184.216.34
使用 host 命令（Linux/Unix）
在Linux和Unix系统中，可以使用 host 命令来查询域名对应的IP地址，打开终端,输入以下命令：
host example.com
你会看到类似如下的输出：
example.com has address 93.184.216.34
通过在线工具查找
除了命令行工具，还有许多在线服务可以方便地查询域名对应的IP地址，这些工具通常提供直观的界面和丰富的功能,以下是一些常用的在线工具：
WhatIsMyIPAddress（whatismyip.com）
这是一个简单易用的在线工具，不仅可以查询自己当前的IP地址，还可以查询任意域名的IP地址，只需在网站首页的输入框中输入域名，点击“Lookup”按钮即可，https://www.whatismyipaddress.com/ ,你会看到类似如下的结果：
