An Internet Protocol (IP) address is a logical address used to route data packets across multiple interconnected networks. IPv4 addresses use a numeric format (such as 192.168.1.5) yielding about 4 billion possible addresses, whereas IPv6 uses longer addresses to provide a vastly larger pool. Rather than pinpointing a physical location, an IP address designates a network or region, and multiple host devices can share a single public address via Network Address Translation (NAT).

IP Address

The Domain Name System (DNS) is an Internet service that serves as a directory or "phone book" for network communication. It translates human-readable domain names (such as example.com) into the numeric IP addresses required by host machines to locate and communicate with each other, eliminating the need for users to memorize numerical addresses.
