I'm wondering if it is possible to specify, that all connections (even future, like when using wifi at some other place (=different SSID)) will be using pre-defined DNS server When I have some (concrete) connections, I could go to IPv4 settings, and specify DNS server there (however, in case of new connection I would have to do it (and not forget it)) This may be particularly useful for some safe/filtering dns (such as opendns's 208.67.222.123 & 208.67.220.123)
