In a typical home environment, the Internet provider will allocate the IP address for your home router. Your home router will, in turn, allocate an IP address for your home computer(s) and other home internet devices to use. The allocated IP addresses will often be allocated from the private 192.168.0.x range. (See https://tools.ietf.org/html/rfc1918 for details on the 192.168.x range)
Yes I know, I was trying to make it simpler for the OP who doesn't seem to know much about IP numbers.
