public open resolver list?

is there a list of public resolvers? e.g. 1.1.1.1, 4.4.4.4, 8.8.8.8, etc.? we have a measurement set which contains a list of 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. the open resolver finders would seem not to meet our need. but, yes, it would be nice if they documented the intentional public open resolvers. randy
