Having name resolution problems connecting to rpmfusion, Below is error 
message.

/etc/resolv.conf has correct settings for nameserver 172.16.0.1 for 
gateway router


# yum update
Loaded plugins: refresh-packagekit
Could not retrieve mirrorlist 
http://mirrors.rpmfusion.org/mirrorl...a-11&arch=i386 
<http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-11&arch=i386> 
error was
[Errno 4] IOError: <urlopen error [Errno -3] Temporary failure in name 
resolution>
Error: Cannot retrieve repository metadata (repomd.xml) for repository: 
rpmfusion-free. Please verify its path and try again


This is the line I put in /etc/modprobe.d/dist.conf for Ipv6 disable

install net-pf-10 /bin/true

It didn't seem to have "name resolution" problems when I downloaded the 
rpmfusion-release-rpm using rpm -ivh .
