Actually that's what I would call a broken IPv6. If that happens for IPv4 
you would switch to another provider. For IPv6 you assume the application 
should fix it. JOSM does not offer that feature due to the missing support 
for this in main Java and not enough reasons to reimplement that 
ourselves.

Another solution compared to disabling IPv6 totally would be to add the 
IPv4 addresses of the non-working servers to your /etc/hosts (path correct 
for Mac?). This changes the resolvers answers, so JOSM will not know that 
these serves have IPv6 and also not try it for these, but for all the 
others.

Anyway the correct solution would be to get your provider to fix the 
routing or change provider.
