I just confirmed that Winbox 3.0 still has the behavior where typing a hostname into “Ping To” will use the client’s DNS resolver, and not the remote Mikrotik’s. I put a hostname into the ping tool, and the Mikrotik tried to ping to my office’s internal IP and not the public IP that external hosts would get from DNS.
