Looks good.

Looks like what is to be expected, too.
And doesn't explain why www.google.com resolves to 1.0.0.0.

Then I'm out of ideas.

Just a last shot in the dark: since update manager tries to connect to
an IPv6 address - do you see any improvement if you disable IPv6?
You could add
ipv6.disable=1
to the boot options.
Easier, and maybe something worth trying first, is disabling IPv6 only
for Firefox: Type
about:config
in the URL bar and press return, accept the warning, and type ipv6 in
the filter bar. You should see the
network.dns.disableIPv6
entry. Double click it to change it's value tor true.
Does that cause any improvement?
