There are several types of addresses that can be used to identify a computer on a network, including:
IP Address: An internet Protocol (IP) address is a unique numerical label assigned to every device connected to the internet. An IP address allows devices to communicate with each other over the internet or a local network.
MAC Address: A Media Access Control (MAC) address is a unique identifier assigned to the network adapter of a device. MAC addresses are used by the low-level network protocols to identify a device on the network.
Hostname: A hostname is a human-readable string that can be used to identify a device on a network. Hostnames can be translated into IP addresses by the Domain Name System (DNS).
In a local network, IP addresses and MAC addresses are the primary means of identifying devices, used to identify resources on the internet.

The two types of addresses used to uniquely identify a computer on a network are the IP address and the MAC address. The IP address is assigned to each device for communication over a network and can change depending on the network. In contrast, the MAC address is a hardware identifier that is permanently assigned to the network interface card (NIC) of the device, ensuring it remains unique regardless of the network it connects to.
In computer networking, a node refers to a connection point. It has two types of addresses, a network address and a physical address.
Internal addresses are hidden from external networks A company needs fewer registered IP addresses to access the Internet
A typical IP address takes the form of 256.256.256.256 - Each IP address is unique - and identifies a single computer connection.
Routers primarily use IP addresses to identify devices on a network and facilitate communication between them. They employ both IPv4 and IPv6 addresses, depending on the network configuration and requirements. Additionally, routers use MAC addresses for data link layer communication to direct packets within a local area network (LAN).
So the network can correctly identify you, personalize settings for you, and allow you connection to the network (or internet).

IP address
If you are using a DHCP server, you are basically safe. It's a good practice to release all ip addresses after certain time especially if you have temporary computer in the network.
