在数字化时代，域名和IP地址是互联网运行的基础，域名是用户友好的名称，而IP地址是计算机之间通信的标识符，有时，我们需要查找一个域名对应的所有IP地址，无论是出于网络管理、安全分析还是其他目的,本文将详细介绍几种常用的方法来查找一个域名对应的所有IP地址。

使用命令行工具
1 nslookup 命令
nslookup 是一个用于查询DNS记录的工具，它可以用来查找域名对应的IP地址,在命令行中输入以下命令：
nslookup example.com
这将显示该域名的IP地址，如果你希望获取更多的IP地址（例如A记录和AAAA记录）,可以使用：
nslookup -query=A example.com nslookup -query=AAAA example.com
2 dig 命令
dig（Domain Information Groper）是一个功能强大的DNS查询工具，可以获取更详细的信息,使用以下命令：
dig example.com +short
这将返回所有A记录和AAAA记录对应的IP地址，如果你需要更多信息，可以省略+short参数：
dig example.com
3 host 命令
host 是另一个简单的DNS查询工具，类似于 nslookup,使用方法如下：
host example.com
这将显示域名的IP地址和其他相关信息。
使用在线工具
1 搜索引擎查询法
在搜索引擎中输入域名并加上关键词“IP”，
example.com IP
搜索引擎会返回该域名的IP地址，这种方法简单快捷，但可能无法获取所有IP地址,尤其是那些不公开或隐藏的IP。
2 专业DNS查询网站
有许多专业的DNS查询网站可以查询域名的所有IP地址，
- Whois：提供详细的域名信息,包括DNS记录。
- DNSStuff：提供多种DNS查询工具,包括DNS记录查询。
- IP-API：可以查询单个IP地址的详细信息,也可以输入域名获取相关信息。
- MXToolBox：提供全面的DNS和邮件服务器信息。
- DNSMadeEasy：提供免费的DNS记录查询工具。
这些网站通常提供直观的界面和丰富的功能，用户可以轻松获取所需的DNS记录，在Whois网站上输入域名后，可以看到详细的DNS A记录和AAAA记录。
使用编程语言和API接口
通过编程语言和API接口，可以自动化地获取域名的所有IP地址,以下是一些常用的方法和示例代码：
1 Python 和 dnspython 库
dnspython 是一个用于操作DNS的Python库，可以方便地查询DNS记录,首先安装库：
pip install dnspython
然后可以使用以下代码查询域名的A记录和AAAA记录：
