FWIW, what you are doing was the advice when IPv6 was introduced, but it was changed. The advice now, is to prefer an end-to-end 4-4 connection over a 4-6-6-4 as the latter introduces considerable inefficiencies and slowdowns to the net as a whole. If you really have a native 6-6, that's preferred, but a 6-6 that is really a disguised 4-4 is wasting BW.
I don't sent IPv4 over IPv6. I tunnel IPv6 and IPv4 goes per usual. Regardless, the problem was accessing a DNS server. My understanding is that with multiple servers listed, if one fails, it moves onto the next. This worked fine for 4 years, with the IPv6 DNS listed first and the IPv4 at the end. When my tunnel started up, it would use the IPv4 DNS to get the server address and go from there. Once the tunnel was up, then the IPv6 DNS servers would be used. I verified this with Wireshark. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
