It could. If the router's WAN was IPv6 but your LAN was still IPv4, you need a 6-to-4 translation in the router in order to communicate from the LAN to the Internet and back. > My guess is that if it would affect the router, that there would be > zero connectivity rather than spotty connectivity. Actually it's not clear. With mixed IPv6 + IPv4 setups I've heard there are situations where IPv6 <-> IPv6 works and IPv4 <-> IPv4 works, but IPv4 <-> IPv6 doesn't. (IIRC) Additionally DNS works differently between the two also: IPv6 records are "AAAA" records, IPv4 records are "A" records -- so the addresses to connect to for services are often different from IPv6 vs IPv4. I don't have much expertise in this area, as I haven't (yet) tried using IPv6 for my own LAN or Internet connection so far. -- Chris -- Chris Knadle chris.kna...@coredump.us _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org https://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) Vassar College * May 4 - Front-End Web Cli Tools Jun 1 - Selinux Jul 13 - Mad Science Fair Vi @ Lourdes
