Does that then imply that machines which do have an AAAA will not be used / served for A records ? ( or tested for that matter )
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.
