I know Google Fiber generation 1 setups were Fiber to the home (to a “Fiber Jack”) with a provided router that had 1 gigabit Ethernet port and a coax/MoCA output. Then each TV receiver box got its connectivity via MoCA (most if the customer homes were already set up for cable to any area there was a TV) and put out 100mb ethernet from each of those endpoints.

What I’ve never heard of is an ISP offering a MoCA coax to your house and you having only a MoCA receiver. Seems more likely the person asking the question actually just has a cable modem and could put their own router downstream of it if they wanted?
