TCP/IP Lab

Purpose of lab:
  Use the ipconfig /all utility to identify the TCP/IP address, subnet mask, default gateway of a computer, the DHCP server that provide the IP address of a computer, and to determine when the lease for that address was obtained and when it will expire.
Note: in Linux, type ifconfig instead of ipconfig.

·         Use the ping utility to contact other computers on the network and remote computers.

·         Use tracert (trace route) to view the path communications take between two sites.

1.      Select Start, Programs, Command Prompt (or MS-DOS prompt option). If Command Prompt is not available, select Start, Run, type cmd and press Enter or select OK.

2.      To obtain the IP address for your computer, at the C:\ prompt, type ipconfig /all and press Enter.
List the:
Physical address (MAC address):_____________
IP address: _______________
IPv6 address: _______________
Subnet Mask address: _______________
Default Gateway: _________________
IP address of the DHCP server: ______________
When was the lease for the IP address obtained: _________________
When will the lease expire: ______________

3.      Obtain the IP address of any other computer in the lab.
Physical address (MAC address):_____________
IPv4 address: _______________
At the command prompt, type
arp -a
what MAC addresses are shown?

4.      At the C:\ prompt, type ping and the IP address of the other computer listed in step 3 and press Enter.
You should see a message that tells you that the other computer is responding to your ping. Ping is a utility that sends a message out to another computer of device on the network and receives a message back to let you know that your computer is communicating with other devices on the network.
