网络常用测试工具的应用实验报告

常用网络工具的应用一、实验目的：1．了解系统网络命令及其所代表的含义，以及所能对网络进行的操作。

2．通过网络命令了解运行系统网络状态，并利用网络命令对网络进行简单的操作。

二、二、实验仪器设备及器材Window XP 局域网三、实验相关理论1．PING命令是检查网络连接状况的网络工具，可以用它来检测数据包到达目的主机的可能性。

2．Win98：winipcfg或Win2000以上：Ipconfig/all命令显示DNS服务器地址、IP地址、子网掩码地址、默认网关的IP地址。

3．Netstat是显示网络连接和有关协议的统计信息的工具。

Netstat主要用于：网络接口的状况；程序表的状况；协议类的统计信息的显示三个方面。

4．ARP：地址解析协议命令，用于将IP地址解析为MAC地址。

四、实验要求：验前认真预习TCP/IP协议内容，尤其应认真理解WINDOWS网络相关原理；在进行实验时，应注意爱护机器，按照试验指导书的要求的内容和步骤完成实验，尤其应注意认真观察试验结果，做好记录；实验完成后应认真撰写实验报告。
