Hue Bulbs use Zigbee. If hue stops supporting the hub or older devices, you can reset and pair them to anything.
The Hue bridge is IP based but can be controlled entirely over your local network. It’s a slim possibility of something breaking (the mobile app mostly) and then the bulbs are still fine.
