The real problem is that the standard POSIX gethost/getaddr* APIs don't tell you the confidence level of the information they return. Nor do they let you specify a minimum acceptable confidence level when you make a query. (Analogous to the SSFs we use in OpenLDAP.)

Yeah, that would be great. There are, unfortunately, a bunch of problems with those interfaces. Blocking behavior is another problem with them.
