It does link to kdecore.
I'm not sure how to do it the Right Way though, there are two uses of 
gethostbyname():

One is supposed to be used from the proxy script and according to Netscape's 
PAC documentation it is supposed to return a dotted quad or undefined if the 
host doesn't resolve. So, I'm not sure how any of the scripts out there will 
react should that function return an IPv6 address...

The other use is in kpac_dhcp_helper, which is used for DHCP based automatic 
proxy discovery. This protocol is also only defined for IPv4 (I don't know if 
there is something like DHCP for IPv6, but here it's definately not 
supported) - the address returned by gethostbyname() is used as the client 
address sent to the DHCP server, and the message sent there has strict 4 
bytes for the IP
