Actually, no need to do the tests. I know that I’m not using IPV6 with this ISP. What I meant was Firefox under WIN7 seems to cope fine with the default settings. Just browsing the network adapter settings, it looks like it detects that there is no IPV6 connectivity when the network is set up and doesn’t try it again every time you access the internet. Seems a sensible approach. That’s the best guess from an average user. That’s what I would have expected to happen when I unchecked “Enable IPV6” in the 11.4 networking setup, but clearly it didn’t.

That is because the IPv6 stack is built into the kernel and that has to be
disabled in the GRUB boot options.
The bottom line is that IPv6 problems are NOT a bug in openSUSE. The problem is
when the DNS server returns an AAAA record, which indicated that it supports
IPv6, and then does not answer IPv6 queries. When that happens, the initial
query has to time out. If you have that situation, bitch to your ISP. They are
causing the problem. If you would rather not fight them, switch to Google’s
public servers at 8.8.8.8 and 8.8.4.4. As with most things, Google gets it right.
