===================
As you can see, the successful one sent multiple hostnames while the failed one sent multiple IP addresses:

In contrast, another USCMS regional redirector xrootd.unl.edu could return results with and without "-m" option:

I was told their log file showed hostnames were sent even without "-m" option.
For cmsxrootd2.fnal.gov XRootD redirector, I added
xrd.network dnr
option in our server side xrootd.cfg but it seems IP addresses still were sent. Could you please tell how I could force hostnames instead of IP addresses to be sent
when running "xrdfs cmsxrootd2.fnal.gov:1094 locate -d" command?
Thanks in advance for any advice on this.
