If you mean it's checking whether your internet connection in general is working, that works because to look up most hostnames, it has to communicate with a DNS server over the internet. No internet, no name lookup. There are exceptions, of course. Entries in /etc/hosts get looked up from the file without asking a DNS server at all.
