Mac无法连接NAT虚拟机，需要配置DNS网段

问题

1. 无法ping通NAT网段为172.16.1.x的虚拟机

解决方案

1. 查看/etc/resolv.conf中网段配置，修改nameserver为172.16.1.1即可

panzhijie-mac:~ panzhijie$ cat /etc/resolv.conf 
#

nameserver fe80::1xx5:76xx:502e:60
nameserver 172.20.10.1 #修改nameserver为172.16.1.1即可

2. 测试ping命令是否连通

panzhijie-mac:~ panzhijie$ ping 172.16.1.10
