IP (Internet Protocol) addresses are simply strings of numbers that identify particular computers on the internet. IP addresses appear as number sequences that are similar to 127.0.0.1. Every computer that is connected to the internet receives an IP address from the ISP (Internet Service Provider) in order to identify and facilitate cyber communication from that computer to other computers on the network.
Even web sites have IP addresses, which usually indicate the IP address of the web server on which the site is hosted. IP addresses are important in web hosting because some hosting plans provide access to more than one IP address, which makes it easier to authentically diversify your web presence in the eyes of the search engines.
