Need a script to modify the registry

The simplest option is to use the REG utility (already available in Windows) with a simple batch file.

REG ADD HKLM\SOFTWARE\CITRIX\RADE /v AppHubWhitelist /t REG_SZ /d "<server name>;<Server IP>"

If you're after the local servername and IPaddress then use the attached batch file

@echo off

REM Quick clean up from any previous attempts
del %temp%\IP.txt /f /q
set TEMPSTRING=

REM Get the local IP addresses and place them in a file
ipconfig | find "IP Address" > %temp%\IP.txt

REM Parse the file and extract the IP address
for /f "tokens=2 delims=:" %%i in ('type %temp%\IP.txt') DO call :add %%i

REM Run REG.exe to add the registry value
REG ADD HKLM\SOFTWARE\CITRIX\RADE /v AppHubWhitelist /t REG_SZ /d "%COMPUTERNAME%%TEMPSTRING%"

REM Clean up after ourselves
del %temp%\IP.txt /f /q
set TEMPSTRING=
goto :EOF

:add
set TEMPSTRING=%TEMPSTRING%;%1

:EOF
REM That's All!
