Sounds like all changes should trigger notifications. I'm not sure that ipconfig
changes work already.
Maybe you want to add a notification to UpdateIPConfigProperties(), or adapt
this comment to exclude IPconfig (because the notifcation is already sent
through the default network).

It's likely going to be redundant since the network should receive an IPConfig
update also, but I would rather be thorough in case somewhere down the line we
add some device specific UI and rely on this, so I added a call for devices to
UpdateIPConfigProperties and explicitly commented for each if these that they
include IPCongig[s] updates. Good catch.
