dnsmask reads all specified files on startup, creates a list of upstream dns
servers, then chooses the one which "works best" (first querys go round robin,
to measure). If this choosen server goes down, it reelects another one from its
list. Additionally, if any resolvfile gets rewritten while dnsmask is running,
it rereads the file and updates its list.

Its simple as this, but it is not simple to say which server dnsmask will choose ;)
