Answer 1

You can get the network name (SSID) of the currently connected wireless network using the following batch file:

for /f "tokens=3" %%a in ('netsh wlan show interface ^| findstr /r "^....SSID"' ) do @echo %%a

So your batch file would look like:

@echo off
set hostspath=%windir%\System32\drivers\etc\hosts
for /f "tokens=3" %%a in ('netsh wlan show interface ^| findstr /r "^....SSID"' ) do (
  if "%%a"=="OfficeWifi" echo 81.155.145.48 ns1.intranet.de >> %hostspath%
)
exit

Answer 2

to make it simple you could just add :

@echo off

set hostspath=%windir%\System32\drivers\etc\hosts
ping "name of office DC" 
if errorlevel 1 quit    
if not errorlevel 1 echo 81.155.145.48 ns1.intranet.de >> %hostspath%
