Windows Batch File To Set Static IP Address Even if NIC is Renamed

Added by Mark Jacob March 23, 2016

My blog today is not specific to Cisco technologies, but it is something that I found useful in my Cisco classes. I needed a script that would set a static IP address on the network adapter, set a DNS server, and function even if the student had renamed the NIC. Here is the solution that worked for me.

@ECHO OFF
title {Whatever you want to have appear as the window title}
:sn
cd\
cls
set /p sn=What is your student number (between 2 and 18)? 
Note, this script functions per student, but feel free to change your particulars
REM **************Student number error trap**************************
  if %sn% lss 2 goto sn
  if %sn% gtr 18 goto sn
REM *************************************************************

:choice
echo You have entered that
echo your student number is %sn%.

set /p yn=If this is correct, type 'y' for yes or 'n' for no and hit Enter 
The following 4 lines prevents errors if the response is upper case vs lower case
  if %yn%==y goto set
  if %yn%==Y goto set
  if %yn%==n goto sn
  if %yn%==N goto sn
cls
echo Please select 'y' or 'n'
goto choice

:set
cls
echo Prepping your computer for the troubleshooting lab.  Please wait...
The timeout is not required, I just configured it so it looked busier 
timeout 5
for /f "skip=4 tokens=5*" %%i in ('netsh int ip show int') do echo %%i %%j> tmpvar
In my case, the output I needed started at the fifth ‘chunk’, so my tokens started at 5.

You can view the output of what I am parsing on your machine by typing
netsh initerface ip show interface and locate the desired output
set /p IN= < tmpvar

netsh interface ipv4 set address name="%IN%" source=static 10.%sn%.10.100 mask=255.255.255.0 gateway=10.%sn%.10.10
netsh interface ipv4 set dnsservers "%IN%" static 8.8.8.8 primary > nul
The ‘> nul’ guarantees nothing is sent to the screen so the student sees no output besides the ‘echo’ statements.
echo Your computer is now ready for the lab
pause
exit

@ECHO OFF

title {Whatever you want to have appear as the window title}

:sn

cd\

cls

set /p sn=What is your student number (between 2 and 18)?

Feel free to mod this script to meet your specific needs.

If you have any comments or questions, please feel free to post them….

Until next time.
