分享一个获取没有被污染 IP 地址的方法

1、获取本机DNS服务器的外网IP。
$ nslookup ip.n.yiz.me
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
Name: ip.n.yiz.me
Address: 58.217.249.156

2、获取没污染的IP
$ nslookup www.twitter.com.n.yiz.me
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
www.twitter.com.n.yiz.me canonical name = twitter.com.n.yiz.me.
Name: twitter.com.n.yiz.me
Address: 199.59.150.39
Name: twitter.com.n.yiz.me
Address: 199.59.149.198
Name: twitter.com.n.yiz.me
Address: 199.59.148.82
Name: twitter.com.n.yiz.me
Address: 199.59.150.7

当然了，至于你能拿这个去干什么用就不知道了。估计也没啥用处。^_^
