A Linux workstation is unable to resolve internet hostnames, but internal hostnames work. The /etc/resolv.conf file is managed by systemd-resolved.

A user reports intermittent connectivity to a remote server. The administrator runs `ping -c 100 remote-server` and sees packet loss. The administrator then runs `traceroute remote-server` and notices that packets stop at a specific router (10.0.0.1) and do not go further. The administrator can ping 10.0.0.1 successfully. What is the most likely cause of the issue?
