What used to be is not necessarily the way it is now and if you lock
into specific DNS server addresses instead of letting them get assigned
via DHCP (as in having a cable modem or DSL modem that gets address
assignment from the provider), then yeah, you might run into issues.

I also run my own DNS servers but that's because I want private LAN
names and e-mail to resolve and I get the added benefit of being able to
flush the DNS cache whenever I choose but for just about everyone I
know, there really is no need to run your own DNS server.
