Could you explain what is meant by 'node address' in networking technologies?

In network technologies, a "node address" refers to a unique identifier of a device (computer, server, router, etc.) in a network, which allows other devices to locate and interact with it. Most commonly, this is an IP address — a numerical code, for example, in IPv4 format (such as 192.168.1.1) or IPv6. The node address is used for data routing and unambiguous identification within the network.
