This problem showed back up this morning. This morning the kernel was
updated to 4.20.13-200 and the machine was rebooted.

This IP address problem, Bash's reverse search not working, missing
utilities, ...
For the reverse search I suggest filing a bug with bash [1], all the
utilities you're missing should be installable with dnf (you don't
actually mention what you think is missing) and the IP address is a
hard one, network issues are very dependent on the local network to
debug.
