== Master Mirror Setup

The master mirrors are accessible as:

....
dl01.fedoraproject.org -> 38.145.32.22
dl02.fedoraproject.org -> 38.145.32.23
dl03.fedoraproject.org -> 38.145.32.24
dl04.fedoraproject.org -> 38.145.32.25
dl05.fedoraproject.org -> 38.145.32.26
....

from the outside. ``dl.fedoraproject.org`` is a round robin to
the first three of these IPs.

External IP addresses map to internal hosts
``dl0[1-5].rdu3.fedoraproject.org``:

....
dl01.rdu3.fedoraproject.org -> 10.16.163.49
dl02.rdu3.fedoraproject.org -> 10.16.163.50
dl03.rdu3.fedoraproject.org -> 10.16.163.51
dl04.rdu3.fedoraproject.org -> 10.16.163.85
dl05.rdu3.fedoraproject.org -> 10.16.163.84
....

Legacy host names ``download[1-5].fedora.redhat.com`` are CNAMEs for
``dl0[1-5].fedoraproject.org``.
