To view the routing table on the current machine, use netstat –r netstat –r What is the IP address of the Gateway? d. How many entries are in the routing table in c? e. To display the statistics for only the TCP protocol, type the following command: netstat –sp tcp How many TCP segments were retransmitted? f. Based on e, how many current TCP connections are there?
