MR60 - IPv6 Internet Connection Type

[ivan42295]

I have a Nighthawk MR60 Router that I just set up at home. I have Google Nest devices that required to activate IPv6 through my admin login. 

My confusion is around all of the different "Internet Connection Types" such as:

Auto-Detect

6to4 Tunnel

DHCP

PPPoE

6rd Tunnel

Pass Through

Fixed

etc. 

I am not sure which one to select for my setup. I tried Auto-Detect and applied the settings. it put me on DHCP, but should it be? 

What are the differences and how should I configure it based on my needs?
