The address of each device in an IP subnet (a kind of subset of complete IP range) should always be unique means no two devices on the same subnet can have the same IP address, otherwise, it will cause an IP address conflict.įor IPv4, its format can be 4 octets like x.x.x.x where each octet is 8 bits or 0 to 255 in decimal. One of the most common and popular examples of a network built on IP addresses is World Wide Web and Internet. An IP (Internal Protocol) address is a unique identifier that identifies a device on the internet-connected to the TCP/IP protocol and enabled communication over it.
