There's a yes and no answer to that, it will depend on the application. I've found that mplayer would first try IPv6, wait for that to fail, then try IPv4, before playing a file. It tries IPv6 because I had IPv6 on my LAN, as far as my router, but my ISP doesn't support IPv6 (so I'd need access to an external gateway). If I totally removed any IPv6 networking from my LAN, it was quicker to start playing streams. Though, the odd thing is that even without IPv6 networking, my DNS server still returns answers for IPv6 addresses (it can still do that through whatever means it has of getting out into the internet). So, to really stop mplayer from always trying IPv6 first, I had to configure mplayer not to do that. Chances are you may have to do that with your browser. Because if anything gives it an IPv6 answer for an address that you're trying to browse (whether that answer comes from your DNS server or a proxy server), it's going to try *it* first. I think that our ISPs are really dragging their heels on this. IPv6 has been around for years, they've been replacing networking equipment for years, it's well past the point where we should have working IPv6 as a matter of course. * In this case the ISP "doesn't support" IPv6 meaning that it's not there, rather than they simply won't give any help with it. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.
