my network consists of 2 desktops wired directly to one another and a laptop. no proxy.

I have already fixed this problem btw if you didnt read that. i changed the DNS server ip. either way, my laptop doesnt have ipv6 installed and this one does so im guesing that this is the problem.

Im aware of what ipv6 is for, longer ip addresses right? for when ipv4 is all used up? but why do i have it on my pc now? does it do anything at the moment?
