Hi

Currently using mesh network made up of XE200, X75 and X50 Outdoor. 
 

Please can someone explain to me the difference between setting up an IoT network vs a guest network to use for separating out a group of devices?

I recently started using the guest network to improve connection with Ring Devices (as suggested in multiple other threads) but am wondering if I would be better to use an IoT network. 

Are there any advantages of one vs the other or are they the same thing except for name?!

Thanks
