IP Address is an abbrevation for "Internet protocol Address" which connects all computers threw a network we call the "internet". IP addresses function much like say your phonenumber or street number, so that one computer can find another one and connect to it. All IP addresses are put into Netblocks and assigned to each country, for example 67.159.0.0/18 or 67.159.0.0 - 67.159.255.255 which is 255*255 = 65,025 IP addresses on that Netblock.
