Here's my current scenario, I have a total of 3 rockets, one of which is already linked to mac address for the IPTV.

One of my two other rockets is connected to a Dreamlink T4. One is being used and the other is inactive.

I plan on getting two more MAG254 and plan on using the rockets from the Dreamlinks.

Since I don't have the MAC addresses for the IPTV just yet, can I make a bogus MAC address for the two rockets I have remaining and change the MAC address later?

Thanks in advance.
