Description: The Network Discovery Protocol (NDP) is a set of protocols used to discover devices on a network, facilitating communication and IP address management. This protocol is fundamental in networks based on Internet Protocol version 6 (IPv6), allowing devices to identify other devices on the same network, determine their link-layer addresses, and resolve network addresses. NDP replaces the Address Resolution Protocol (ARP) used in IPv4, offering a series of improvements in terms of security and efficiency. Among its main features are address autoconfiguration, duplicate address detection, and the ability to discover routers on the network. Additionally, NDP uses ICMPv6 messages to carry out its functions, enabling more effective communication between devices. The relevance of this protocol lies in its crucial role in the implementation of IPv6, which is essential for the continued growth of the Internet and the connectivity of devices in an increasingly interconnected world.
