I just have a theoretical question. If a computer is connected to a router, then of course the default DNS server on the PC itself will show the 192.x for the router. What would be the effect of going into the TCP/IP properties and changing the DNS server from the router, to something external such as 4.2.2.1? How would hostnames be resolved in this case? Generally in this type of case it's better to make the DNS server changes in the router itself and not the computer right? Specifically I would like to know the effect of doing this. Thanks.
