Testing reachability to a host and identifying the path taken is about verifying connectivity and mapping the route your packets follow. Ping checks connectivity by sending ICMP echo requests and waiting for replies, giving you a yes/no answer on reachability plus round‑trip time and any packet loss. To see the actual route, use a traceroute tool that probes with increasing TTL values so each router along the path replies back, letting you see the sequence of hops and their addresses with response times. In MikroTik, that combination is achieved by using ping to confirm the host responds and traceroute to reveal the path. Keep in mind some networks may block ICMP or deprioritize traceroute, which can affect results. Other tools like a packet sniffer or just viewing the routing table don’t directly show reachability or the forward path to a specific host.
