The related ping utility is implemented using the ICMP echo request and echo reply messages.

Then, the command ipconfig /renew is executed to request a new IP address. [ 3 ] [ 4 ] Where a computer is connected to a cable or DSL modem, it may have to be plugged directly into the modem network port to bypass the router, before using ipconfig /release and turning off the power for a period of time, to ensure that the old IP address is ...
