I cannot reproduce this. Must have been on IPv6-day!?
What is the exact situation? The patch isn't correct. If anything is
wrong then it might be that we need to use the gethostbyname-based
implementation in even fewer situations or the getcanon implementation
has a problem.
The 1e100.net address obviously also belongs to Google. Therefore I'm
not really sure there is a problem. They might have directed IPv4 and
IPv6 traffic to completely different machines.
