Hi

I'm having trouble configuring my ATV4 to permit access to Rugby Pass (via the app) to stream geo-blocked content to my TV. I've got a post about that, however thought I'd start a new thread here, to hopefully get a better understanding of the dangers I'm possibly exposing myself to by changing the DNS settings of the various devices, in order to access the geo-blocked content. I have little (ok, none!) understanding of how the traffic/data moves to/from the router/computer - but my concern is (possible unwarranted) that I'm exposing myself to danger by routing traffic through DNS4me's servers.

1. What impact does changing the DNS server addresses in the router, to the DNS entries supplied by DNS4me, actually have? Does this mean ALL traffic is routed through their servers? 

2. If the answer to the above is "yes" - isn't that bad? Doesn't it mean slower transfer speeds and possible security issues given that DNS4me can potentially observe any data I pass through the router?

3. Could I avoid the above situation by establishing a static route in the router, using the guide on DNS4me?

4. Or do I have totally the wrong end of the stick? Maybe the DNS server doesn't actually route data - and is merely a directory type service???

Any help much appreciated - even if it's to point me in the direction of a guide so I can educate myself about this network thing and therefore better understand it! I don't really understand what the various IP addresses are, DNS entries, how data gets from device to device etc etc.
