What is my Flex IP address?
I'm trying to track down the source of excessive bandwidth consumption using the bandwidth meter on my own router and I needed to know the IP address of my Flex box to see where it was in the list of devices. I pulled up the Flex settings and couldn't find any place where it would tell me the IP address.
I did find the MAC address printed on the bottom of the box, but it doesn't match the one in my DHCP log. It's off by one! Then I realized the MAC printed on the bottom is that of the WiFi, which I'm not using. The MAC of the wired interface is one less than the WiFi's MAC (in my case, 84 instead of 85). With that insight, I was able to look in my DHCP log and spot the address that the Flex was using.
(I'm not using xFi because my modem is in bridge mode, because I want my LAN's DHCP server to assign addresses, not my Xfinity modem. Please add a feature to disable the IPv4 DHCP server on the modem.)
For others seeking a bandwidth monitor, I'm using OpenWrt firmware on a ZyXEL router and have the nlbwmon and luci-app-nlbwmon packages installed. The first package collects the data and the second provides a nice display of it in the router's web interface.

I have an Xfinity Flex Xi6-T. When I went looking for the wifi MAC address of course tech support was unable to help, but with enough investigating I was able to determine it by a process of elimination. And for me, the one printed on the bottom was the wired etherned MAC, which I am not using. The wifi MAC address was the printed wireline ethernet address minus two (wired ethernet ends in 8C, wifi ends in 8A).

I'll bet there's another interface that uses the -1 address, between the other two. Does your Flex support dual-band WiFi? Perhaps the other band gets the middle MAC address.
