KExtendedSocket async lookup

After looking into the KExtendedSocket code I noticed that async lookups use
the QDns class. Doesn't this imply that the lookup results for sync and
asynced mode operation can vary wildly since QDns does not take into account
/etc/hosts among others?
Related to this differences, netsupp.cpp has a test for the availability of
IPv6 but the async lookup code does not seem to check that and do a IPv6
lookup in all cases.
As of last year there were still a lot of nameservers out there that don't
properly handle IPv6 lookups (bbc.co.uk the most well known) so not being
able to disable IPv6 lookups is a problem. (See e.g. BR30078)
