Whether it works for you is irrelevant, wget has to work everywhere, 
including networks that aren't configured for IP6.

Since _I_ don't take special action to support IP6, probably it falls 
over at my Internet gateway where IP6 traffic has to be mapped into IP4 
and NAT.

I don't imagine I'm Pat Malone here.
