Comment 73 for bug 313218

I'm sorry to say that all of you have gone too far in the debris of protocols putting aside the possible workaround...
I'm from Ukraine and I confirm that connection became slow with this new 9.04 release.
As 'sojourner' already told there was an excellent fix for that in the past (blacklisting the 'ipv6' in /etc/modprobe.d/alieses).
Can anyone tell the new fix for that? I mean can I still blacklist ipv6 because its unsupported in my country at all.
