Conditional based on current IP

Hi guys, I'm after a batch script which will check the current IP of the machine and if it falls within a list of certain ranges, go to another section of the script.

So something like this:
IPrange1 = 1.1.1.x
IPrange2 = 1.1.2.x
IPrange3 = 1.1.3.x
If current IP address is in IPrange1 goto range1
If current IP address is in IPrange2 goto range2
If current IP address is in IPrange3 goto range3
.....

On phone at mo. so can't type it out here but this is pretty well what a script of mine here does:

have a look and can help customise if needed.

The proper construct should look something like this:

@echo off

for /f "tokens=2 delims=:" %%a in ('ipconfig ^| find "IPv4"') do (
  for /f "tokens=3 usebackq delims=." %%b in ('%%a') do goto range%%b
)

exit /b

:range1
  echo Range 1
goto :eof

:range2
  echo Range 2
goto :eof

:range3
  echo Range 3
goto :eof

:etc...

Nice oBdA..

An easy quick way if in a specific environment is to check simply using ipconfig, i.e.

ipconfig | find "1.1.2." && echo I am on subnet with 1.1.2. in it

paul - works OK unless on pre-IPv6 machine like XP though.

There may also be other better ways depending upon WHY you want this, such as using DNS to provide an IP in the same subnet based on the same name with multiple records, using DFS for a drive mapped to local server etc.

Oops! I meant...

@echo off

for /f "tokens=2 delims=:" %%a in ('ipconfig ^| find "IPv4"') do (
  for /f "tokens=3 delims=." %%b in ('echo %%a') do goto range%%b
)

exit /b


:range1
echo Range 1
goto :eof

:range2
echo Range 2
goto :eof

:range3
echo Range 3
goto :eof

:etc...
