Running repoquery command on a AWS instance results in a "Could not resolve host: xxx.com; Name or service not known"

Issue

• Running the repoquery command fails with the following error:

# sudo repoquery '*' --pkgnarrow=updates

• The issue is generally seen after a reboot, and resolves itself once repoquery has been run once.
