When you tracert a destination IP address, the default behavior is to trace the route and report the round-trip time, the near-side router IP address, and the DNS name corresponding to the near-side router IP address. When you tracert a name, normal name resolution techniques resolve the name to an IP address before the ICMP Echo messages are sent.
