dnswatcher never asks for recursion, so a reply marked recursion available comes from a resolver on the network answering in the server's place, as on a network that sends all DNS to one resolver. Such a resolver answers only from its cache, or with SERVFAIL or REFUSED, which made make check fail there. A reply over UDP marked so is now asked again over TCP, which many such networks leave alone, and the TCP reply is used. A reply from a root server's address still marked so is not used, and when every root server refuses or gives one, the error is the existing "this network intercepts DNS queries". Model: opus-5-5
