[CentOS] Yum Weird Message

I ran into this exact issue last night -


When a computer is connected via IPv4 but the IPv4 a repo host connects 
to is not available, yum then tries the IPv6 address and will fail with 
a confusing message telling you it failed to connect to the IPv6 address.

I don't know if there is a way for yum to figure out whether the current 
network connection to the Internet is IPv4 or IPv6.

But if there is a way, it might make a usability improvement. A lot of 
people have no idea what IPv6 is and would be confused.

I was confused myself at first, wondering if DHCP pulled in IPv6 from 
the router.
