IP分片 ping 的工作原理 ip protocol header size: 20bytes <= ip header size <= 60byte ip4 range: 0.0.0.0 ~ 255.255.255.255; 2 * 32 ip(4.3billion); why need ip layer? if we connect all computer, we must group the mac; mac address is hard for group; ip is a virtual address which easy to group , so we can build a big network; divide the addrees why? to reach the destination more efficiently
