Roamio on 2 Internal IP addresses?

I have a Roamio Plus and 2 Mini's on my network, however the attached devices list on my router shows 4 Tivos on my network with the TSN of the Roamio showing up on 2 different IP addresses. What's especially weird about it is that it shows 2 different MAC addresses as well. They are almost identical but one ends in DE and the other in DF. When I type the IP address of the ghost Tivo in my browser I can log into it with my MAK number but after logging in the page says Resource not found. Doesn't seem to cause any problems but I am really curious as to where it's coming from. I have mixed ethernet + moca network. Is that causing it?
