Protocol Length:协议长度 Operation Code:ARP报文的类型,Request/Reply Source Hardware Address:源MAC地址 Source Protocol Address:源IP地址 Destination Hardware Address:目的MAC地址 Destination Protocol Address:目的IP地址 ARP报文不能穿越路由器,不能转发到其他广播域 1、比如主机A去访问主机C,则需要先获得C的MAC...
Hardware Length和Protocol Length为MAC地址和IP地址的长度,单位是字节; Operation Code指定了ARP报文的类型,包括ARP Request和ARP Reply; Source Hardware Address指的是发送ARP报文的设备MAC地址; Source Protocol Address指的是发送ARP报文的设备IP地址; Destination Hardware Address指的是接收者MAC地址,在ARP Request报...
1. Location: The source code for the `arp` command is located in the `arp.c` file in the `net-tools` package. This package contains a collection of tools for managing and monitoring network connections in Linux. 2. Code Structure: The code is written in C programming language and follow...
Destination address(目标MAC地址): 占6个字节,如果是ARP请求帧,因为它是一个广播帧,所以要填上广播MAC地址 -- FF-FF-FF-FF-FF-FF,其目标是网络上的所有主机。 Source address (源MAC地址): 占6个字节,发送ARP帧的节点的MAC地址。 Type (类型): 占2个字节,用来标识帧封装的上层协议,因为本帧的数据部分...
