Finalsite adds new servers as needed and adjusts the servers that schools use in order to balance load inequities that arise. As such, it is best to whitelist the full range of our Messages IP addresses. It's not prudent to whitelist only the server you currently use, as it is not possible to say your IP will always stay the same.
