An Internet Protocol (IP) address is a logical network-layer identifier assigned to a device to enable addressing and the routing of packets across multiple interconnected networks. Rather than identifying a permanent physical hardware interface or pinpointing an individual's exact physical location, an IP address typically specifies a device's network or regional presence.

IP Address

The Internet Protocol (IP) is a core network protocol responsible for addressing and routing data packets from a source device to a destination device across multiple interconnected networks using IP addresses.

Best-effort delivery is a network transmission model in which a protocol attempts to route and deliver packets to their destination without providing any guarantees regarding arrival, sequence order, or transmission speed.

Best-Effort Delivery

IPv4 and IPv6 represent two generations of Internet Protocol addressing schemes. IPv4 uses 32-bit addresses displayed in dotted-decimal format (such as 192.168.1.5), providing approximately 4 billion unique addresses; because this address pool became depleted as global internet connectivity expanded, IPv6 was introduced with significantly longer address lengths to accommodate a vastly larger universe of network devices.
