1.实验环境

主机A和主机B通过一根网线相连

2.需求描述

为两台主机配置IP地址，验证IP地址是否生效，验证
同一网段的两台主机可以互通，不同网段的主机不能
直接互通

3.推荐步骤

1. 为两台主机配置P地址，主机A为10.0.10.10，主机B为10.0.11.11配置子网掩码
均为255.255.00

2.通过 ipconfig 命令验证主机IP是否生效

C:\>ipconfigFastEthernet0 Connection:(default port)Link-local IPv6 Address.........: FE80::2D0:58FF:FEA8:EE60IP Address......................: 10.0.10.10Subnet Mask.....................: 255.0.0.0Default Gateway.................: 0.0.0.0Bluetooth Connection:Link-local IPv6 Address.........: ::IP Address......................: 0.0.0.0Subnet Mask.....................: 0.0.0.0Default Gateway.................: 0.0.0.0

C:\>ipconfigFastEthernet0 Connection:(default port)Link-local IPv6 Address.........: FE80::290:21FF:FE09:2730IP Address......................: 10.0.11.11Subnet Mask.....................: 255.0.0.0Default Gateway.................: 0.0.0.0Bluetooth Connection:Link-local IPv6 Address.........: ::IP Address......................: 0.0.0.0Subnet Mask.....................: 0.0.0.0Default Gateway.................: 0.0.0.0

3.通过 ping 命令验证两台主机是否互通

C:\>ping 10.0.11.11Pinging 10.0.11.11 with 32 bytes of data:Reply from 10.0.11.11: bytes=32 time<1ms TTL=128
Reply from 10.0.11.11: bytes=32 time=4ms TTL=128
Reply from 10.0.11.11: bytes=32 time<1ms TTL=128
Reply from 10.0.11.11: bytes=32 time=3ms TTL=128Ping statistics for 10.0.11.11:Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:Minimum = 0ms, Maximum = 4ms, Average = 1msC:\>

4.将子网掩码都改为 255.255.255.0，并重复步骤 2，步骤 3

1.将子网掩码都改为255.255.255.0

2.重复步骤2

C:\>ipconfigFastEthernet0 Connection:(default port)Link-local IPv6 Address.........: FE80::2D0:58FF:FEA8:EE60IP Address......................: 10.0.10.10Subnet Mask.....................: 255.255.255.0Default Gateway.................: 0.0.0.0Bluetooth Connection:Link-local IPv6 Address.........: ::IP Address......................: 0.0.0.0Subnet Mask.....................: 0.0.0.0Default Gateway.................: 0.0.0.0C:\>

C:\>ipconfigFastEthernet0 Connection:(default port)Link-local IPv6 Address.........: FE80::290:21FF:FE09:2730IP Address......................: 10.0.11.11Subnet Mask.....................: 255.255.255.0Default Gateway.................: 0.0.0.0Bluetooth Connection:Link-local IPv6 Address.........: ::IP Address......................: 0.0.0.0Subnet Mask.....................: 0.0.0.0Default Gateway.................: 0.0.0.0C:\>

3.重复步骤3

​
C:\>ping 10.0.11.11Pinging 10.0.11.11 with 32 bytes of data:Request timed out.
Request timed out.
Request timed out.
Request timed out.Ping statistics for 10.0.11.11:Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),C:\>​

至此实验结束。
