Batch commands to change IP and DNS

Question

I have written few commands in batch to execute them on choice basis. I am using 2 IP addresses for which I have to change IPv4 and DNS every time I switch between IPs.

I have done this code and this works correctly if I execute line by line but in batch they give errors.

@ECHO OFF 
SET /P no= Welcome dude so what are you up to press 1 for buzznet,2 for BSNL :

IF "%NO%"=="1" GOTO BUZZ
IF "%NO%"=="2" GOTO BSNL

:BUZZ
netsh interface ipv4 set address name="Ethernet" source=static ^
      addr=192.168.22.19 mask=255.255.255.0 gateway=192.168.22.1
netsh interface ip add dns name="Ethernet" addr=192.168.18.1
netsh interface ip add dns name="Ethernet" addr=8.8.8.8 index=2

:BSNL
netsh interface ip set address "Ethernet" dhcp
netsh interface ip set dns “Ethernet” dhcp
pause

Solution

As stated in comments you need to add something that stop the script continuing when the job is done. (goto:EOF or exit /b 0)

@ECHO OFF 

:retry
SET /P no= Welcome dude so what are you up to press 1 for buzznet,2 for BSNL :

IF "%no%"=="1" GOTO BUZZ
IF "%no%"=="2" GOTO BSNL
rem if %no% is not 1 nor 2 then exit or goto :retry.
exit /b 0

:BUZZ
netsh interface ipv4 set address name="Ethernet" source=static ^
      addr=192.168.22.19 mask=255.255.255.0 gateway=192.168.22.1
netsh interface ip add dns name="Ethernet" addr=192.168.18.1
netsh interface ip add dns name="Ethernet" addr=8.8.8.8 index=2
rem job done, then exit with a pause before
pause
exit /b 0

:BSNL
netsh interface ip set address "Ethernet" dhcp
netsh interface ip set dns "Ethernet" dhcp
pause

Also the last command are malformed with quotes “Ethernet” should be "Ethernet"
