DOS获取本机IP(括号内的为注释，输命令时别复制进去)。
方法1：arp -a (Interface:后面的就是你自己的IP地址)
方法2:ipconfig/all (IP Address后面的就是你自己的IP地址)
DOS重新获取IP
cmd /c ipconfig /release (释放IP,不执行这步下一步命令将无效)
cmd /c ipconfig /renew (重新获得IP)
上不了网或IP冲突时可以在记事本里贴入如下代码保存为如下文件名并执行：
重新获取IP.bat
@echo off
@echo 正在重新获取IP，请稍候....
cmd /c ipconfig /release > nul
cmd /c ipconfig /renew > nul
arp -a
@echo "Interface:后面的就是你自己的IP地址"
@echo "按任意建测试网络联通(不断跳说明网络正常)"
pause
ping
www.baidu.com -t
本程序在我的XP系统下测试通过。
在执行本程序前请不要绑定网卡IP,否则重新获取IP的二条命令无效。
