Net::DNS does not bind libresolv on *NIX; it does its own parsing
of /etc/resolv.conf.  On Win32, it uses Win32::IPHelper's bindings of
GetNetworkParams.

So this is YA resolver implementation.  When it came to BIND's liblwres,
you asked that it use the Windows APIs in order to ore closely match our
libresolv implementation and not require an /etc/resolv.conf.  The same
would apply here as well.
