Docker网络：MacVLAN与IPVLAN深入解析
1. 网络连通性测试
在开始介绍Docker网络驱动之前，先进行了一些网络连通性测试。例如，对IP地址172.16.10.6进行ping测试，结果显示：
64 bytes from 172.16.10.6: icmp_seq=2 ttl=64 time=0.030 ms --- 172.16.10.6 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 999ms rtt min/avg/max/mdev = 0.030/0.035/0.041/0.008 ms然而，尝试访问父接口（eth0）上定义的主机IP地址172.16.10.2时却失败了：
user@net1:~$ sudo ip netns exec namespace1 ping 172.16.10.2 -c 2 PING 172.16.10.2 (172.16.10.2) 56(84) bytes of data. --- 172.16.10.2 ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 1008ms
)
