There are 2 components:

1) URLs handed to end users.  These are simply URLs, the client (yum,
   browser for download links, ...) does its own address resolution
   and decision as to which IPv[46] address to use.

2) The MM crawler.  It does its own address resolution (via
   urlgrabber), and doesn't try both IPv4 and IPv6 if both types of
   records are available.
