GCSE COMPUTING - IP ADDRESSING AND DNS SERVERS
explain the need for a IP address.
our IP address is like a telephone for our computers/device. we need a IP address so packets know which device/computer to arrive at. for example, if you and someone else both have clicked on a link on your home network, then you wouldn't want to get the other persons page much like they wouldn't want yours. having an individual IP means that you will always get the data that you want instead of someone else's.
