Port addresses and network addresses are two types of:

Port addresses and network addresses are classified as logical addresses because they are used for identifying devices on a network in a way that is not tied to the physical hardware of those devices. Logical addressing allows for more flexible routing of data packets within networks. While the physical address, also referred to as a MAC address, is a unique identifier tied to a network interface card, logical addresses, such as IP addresses and port addresses, can change based on the network configuration, such as when devices are added, moved, or reconfigured.

Logical addresses facilitate communication across multiple types of physical networks and can be used to establish connections between different networked devices, regardless of their underlying physical characteristics. This distinction makes them essential in the functional layers of networking, particularly at the transport and internet layers, where logical addressing is paramount to routing and data delivery.
