This does not work, for two reasons: “>>” is evaluated before the sudo
privilege escalation, and Fedora will not use the host names you

You need to look at the network traffic with Wireshark and figure out
what the original host names are (“sudo tcpdump -i any -s 0 -v port
53” would work as well). This will also tell you what is actually
