网络层主要协议与arp欺骗 一、网络层(Network Layer) 1、网络层的功能 (1)定义了基于IP协议的逻辑地址 (2)连接不同的媒介类型 (3)选择数据通过网络的最佳路径 2、IP数据报(IP Datagram) TCP/IP协议定义了一个在因特网上传输的包,称为IP数据报,由首部和数据两部分组成。首部的前一部分是固定长度,共20字节,...

ARP 协议定义于 1982 年的RFC 826。 (TheAddress Resolution Protocol (ARP)is a communication protocol used for discovering thelink layeraddress, such as aMACaddress, associated with a givennetwork layeraddress, typically anIPv4address.ARPwas defined in 1982 byRFC 826.) ARP 协议在 TCP/IP 协议栈中...
Why bother implementing a network layer protocol in user space? The short answer is “configuration control.” RARP uses the /etc/ethers file or the ethers NIS map to correlate MAC addresses to IP addresses; this is maintained by you, our gentle reader, in the same manner that IP address...
layer addresses. On a single physical network, individual hosts are known on the network by their physical hardware address. Higher-level protocols address destination hosts in the form of a symbolic address (IP address in this case). When such a protocol wants to send a datagram to ...

The Address Resolution Protocol(ARP) is used to associate a three-layer(Network layer) address(such as an IP address) with a two-layer(Data Link layer) address(MAC address).Because of the defects of ARP itself,there are very serious problems in the use of ARP,such as peculating IP(Inter...
