No, the point is that DNS resolvers in different places all use the same addresses. So at the cyber cafe 3003::3003 is the cyber cafe DNS but at the airport 3003::3003 is the airport DNS. (Or in both cases, if they don't run a DNS server, one operated by their ISP.)

I understand people use DHCP for lots of stuff today. But that's mainly because DHCP is there, not because it's the best possible way to get that particular job done.
