Problem is here:
https://www.virtualbox.org/browser/vbox/trunk/src/VBox/Devices/Network/slirp/hostres.c?rev=59202#L408
402 if ( qtype != Type_A
403 && qtype != Type_CNAME
404 && qtype != Type_PTR
405 && qtype != Type_ANY)
406 {
407 LogErr(("NAT: hostres: unsupported qtype %d\n", qtype));
408 return refuse(pData, m, RCode_NotImp);
409 }
They should return RCode_NXDomain instead of RCode_NotImp. Seems like
they also have more of those invalid use of NotImp.
