getaddrinfo resolves google.com fine but when tries to resolve www.google.com (or any fqdn with more than two levels) it fails: "hostname nor servname provided, or not known".
When getaddrinfo tries to resolve www.google.com (for example), in the DNS server I see this query:
07:14:35.038219 IP A.B.C.D.13162 > W.X.Y.Z.53: 3863+ A? group_compat. (30)
07:14:35.038558 IP W.X.Y.Z.53 > A.B.C.D.13162: 3863 NXDomain 0/1/0 (105)
Any clue of what is going on? Thanks in advance.
There was an ugly an subtle bug in the code itself: getaddrinfo hints structure was wrongly populated. Fixing that the application behaves correctly.
