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.
TCP/IP networks use both the IP addresses and MAC addresses of connected computers. A computer's assigned IP address changes over time, but the MAC address of the computer hardware is fixed. In some situations you may know the IP address of some computer and want to determine its MAC address.Answer: It is usually not possible for a person to get the MAC address of a computer from its IP address alone.These two addresses originate from different sources.he technology called ARP-Address Resolution Protocol included with TCP/IP makes it possible. Using ARP, each computer maintains a list of both IP and MAC addresses for each device it has recently communicated with. Most computers allow you to see the list of IP and MAC addresses that ARP has collected there.
