An IP address is a number that identifies your computer and the network area it is a part of. Every device directly connected to the internet has a unique address. Home and office machines typically have IP addresses that reflect the hierarchy of the network they are on. You can think of an IP address as being similar to a postal address. It describes where to send data so that it reaches it's destination.
the IP address is assigned to your computer by your DHCP server you can only have 1 true ip address, although you can have ghost ip address and private ip addresses Private Addresses are not routable through the internet Ghosts IP addresses are normally used to cover something up, usually something illegal ;)
