Answers. Best Answer: 12 hours. Though you can sleep you need to wake up every hour, and doing that is basically the same as getting no sleep. Also, you would need someone else to wake you up every hour and that would disturb their sleep too, so it is easier for everyone if you just stay up the 12 hours.Source(s):Maggie Â· 7 years ago.hough you can sleep you need to wake up every hour, and doing that is basically the same as getting no sleep.

The ping Command. ping is one of the most basic, but also one of the most useful, tools for obtaining information about computer networks, including the Internet. A main use of ping is to determine whether a specific IP address is accessible. An IP address is a unique numeric identifier for a computer or other device on the Internet or other TCP/IP (transmission control protocol/Internet protocol) network.
Arp allows you to view and modify the ARP cache. If two hosts on the same subnet cannot ping each other successfully, try running the arp -a command on each computer to see whether the computers have the correct media access control (MAC) addresses listed for each other. You can use Ipconfig to determine a host's correct MAC address. You can also use Arp to view the contents of the ARP cache by typing arp -a at a command prompt. This displays a list of the ARP cache entries, including their MAC addresses. Following is an example list of ARP cache entries.
