Spoofed Gateway Mac address in 10.2?

Hello all -- Just downloaded the iOS 10.2 beta to test and found a function that is no longer working. In the code below, I've look through the ARP Table to get the Gateway IP. From that, I reverse lookup and get the Gateway's MAC Address. In iOS 10.1, the function below will return a proper MAC Addressin the following style @"08112200FFAA"

Running this same piece of code on 10.2 succeeds but returns a spoofed Mac address, 02:00:00:00:00:00... Seems this maybe a security improvment over 10.1?

Is anyone (@Apple???) able to confirm that 10.2 has infact made a change to block getting a macaddress?
