That's another way of doing it, but it precludes most autodicovery protocols working between wired and wireless devices. Eg you wireless device won't be able to discover a wired printer through mDNS (aka Zeroconf).

That's a significant problem where people want to segregate devices (eg put IoTat one it's own network so it can't blab about other stuff you have) because so much of it is written on the assumption that (eg) your smartphone is on the same network as the device.
