I think this is a reasonable way to do that, hence rsync provides a "-4/-6" option to let you choose which internet protocol to prefer. IMHO it is safer to have a separate v6 DNS. But this is only because there is access authorization done on IP level, in other cases I would strongly encourage to have A and AAAA records for the same name. "msync-v6.centos.org::CentOS" sounds more semtantic to me.
