I've had a quick look at the mirrormanager code from
https://git.fedorahosted.org/cgit/mirrormanager/ and found you can pass
these other parameters with your request:

Also, instead of metalink, the request may be done through mirrorlist.
The output is a simple list, which is easier to parse than the XML
output by metalink.
For example, the following request:
> https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-21&arch=armhfp&ip=0.0.0.0
includes ftp.jaist.ac.jp, as you would expect.
In the code, I came across some comments that mentioned that some
mirrors may be made visible only to other mirrors. So although adding
the ip=0.0.0.0 will give you a more complete list, it would never be a
truly complete list unless you mirror the archive yourself.
A case in point is the Australian mirror that I've always used:
mirror.aarnet.edu.au. It doesn't seem to be officially listed as a
Fedora mirror, yet you already have it included as a Fedora mirror in
apt-cacher-ng.
