2. setlocal enabledelayedexpansion
   
3. 
   
4. set command=" ipconfig /all | findstr /c:"IP Address" /c:"Subnet Mask" /rc:"Gateway.*[0-9].*" /c:"DNS Servers" /rc:"[ ][ ][ ]*[0-9]" "
   
5. 
   
6. for /f "tokens=1,2,*" %%a in (' %command% ') do (
   
7.     if "%%b"=="" (
   
8.         set DNS_Servers2=%%a
   
9.     ) else (
   
10.         set value=%%c
    
11.         set value=!value:*:=!

13.     )
    
14. )
    
15. 
    
16. echo 本机IP为：%IP_Address%  
    
17. echo 子网掩码：%Subnet_Mask%
    
18. echo 本机网关：%Default_Gateway%
    
19. echo 首选 DNS：%DNS_Servers%
