IP Address Definition or Internet Protocol is an address that identifies all devices that connect to the network. An IP address is not a random number, by using mathematical calculation the IANA can produce and locate the value. What is IANA? IANA or Internet Assigned Numbers Authority is a division of theĀ Internet Corporation for Assigned Names and NumbersĀ (ICANN).
ICANN is an organization that started in the United States in 1998 to help maintain the security of the internet and allow it to be usable by all. Each time anyone registers a domain on the internet, they go through a domain name registrar, who pays a small fee to ICANN to register the domain.
Introduction IP Address Definition

How does IP address work?
If you want to understand why a particular device is not connecting in the way you would expect or you want to troubleshoot why your network may not be working, it helps understand how IP addresses work.
Internet Protocol works the same way as any other language, by communicating using set guidelines to pass information. All devices find, send, and exchange information with other connected devices using this protocol. By speaking the same language, any computer in any location can talk to one another.
