5. IP ADDRESS

   • A UNIQUE VALUE ASSIGNED TO EVERY COMPUTER ON A NETWORK, USED TO IDENTIFY IT
   • When the format of IP Addresses were decided in 1983, 4 billion addresses seemed more than enough
   • IP Addresses therefore range from 0.0.0.0 to 255.255.255.255
   • 255×255×255×255 = 4’228’250’625 = THE AMOUNT OF IP ADDRESSES' THE SYSTEM CAN HAVE
