查找微信使用的IP地址：
1、 域名查找
# nslookup
> weixin.qq.com
Server:114.114.114.114
Address:114.114.114.114#53
Non-authoritative answer:
weixin.qq.comcanonical name = minorshort.weixin.qq.com.
Name:minorshort.weixin.qq.com
Address: 140.206.160.234
Name:minorshort.weixin.qq.com
Address: 140.207.54.47
Name:minorshort.weixin.qq.com
Address: 140.207.135.125
2、连接数查找
运行脚本： bash wechat.sh test 123456
多运行几次，查看是否有不同的IP
netstat -nat
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:33197 140.207.127.79:443 TIME_WAIT
tcp 0 0 0.0.0.0:33196 140.207.127.79:443 TIME_WAIT
3、 iptables 配置：
:OUTPUT DROP [8:1128]
-A OUTPUT -d 140.207.127.79/32 -p tcp -m tcp --dport 443 -j ACCEPT
-A OUTPUT -d 117.185.30.190/32 -p tcp -m tcp --dport 443 -j ACCEPT
-A OUTPUT -d 140.207.135.125/32 -p tcp -m tcp --dport 443 -j ACCEPT
-A OUTPUT -d 140.207.54.47/32 -p tcp -m tcp --dport 443 -j ACCEPT
-A OUTPUT -d 140.206.160.234/32 -p tcp -m tcp --dport 443 -j ACCEPT
-A OUTPUT -p udp -m udp --dport 53 -j ACCEPT
