Final answer:
The tool to identify the path of a packet across an internet network is 'Tracert'. Tracert reveals the routers the packet travels through by reporting their IP addresses. It is different from Ping, Ipconfig, and Netstat, which serve other network-related purposes.
Step-by-step explanation:
To identify the path that a packet takes across an internet network, the tool you would use is Tracert (short for Trace Route). This command-line utility is used to determine the pathway taken by packets to reach a specific destination across IP networks. When you execute Tracert, it reports the IP addresses of all the routers the packet travels through to reach its destination, giving you a mapped outline of the packet's journey.
Ping is a tool used to check the reachability of a host on an IP network and to measure the round-trip time for messages sent from the originating host to a destination computer. Whereas Ipconfig is a command-line tool used on Microsoft Windows to display all current TCP/IP network configuration values and refresh Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.
Netstat stands for network statistics. This utility displays network connections for the Transmission Control Protocol (both incoming and outgoing), routing tables, and a number of network interface and network protocol statistics.
