linux下查看一个域名的IP地址

例子：查看www.baidu.com的IP

# nslookup www.baidu.com
Server:         8.8.4.4
Address:        8.8.4.4#53

Non-authoritative answer:
www.baidu.com   canonical name = www.a.shifen.com.
Name:   www.a.shifen.com
Address: 182.61.200.6
Name:   www.a.shifen.com
Address: 182.61.200.7

我们可以看到最后一行，www.baidu.com的IP地址为“182.61.200.7”
