is there a list of public resolvers? e.g. 1.1.1.1, 4.4.4.4, 8.8.8.8, etc.?
interesting, but probably too broad.
but i suspect my question was too broad.
we have a measurement set which contains resolvers, some of which we suspect are intentionally open, some unintentionally open, and some not open. we are trying to filter that first set, the intentionally open.
i suspect it hinges on what one thinks of as 'public'. i.e. dtag's servers for its customers is not what i think of as public. maybe i mean globally public or something.
randy, who clearly needs to think a bit more
