summary addresses
An address that can only be used on the internal network
It can provide a list of physical addresses on the network
compare and contrast the three types of addresses used in a network
A slash 22 network, denoted as /22, refers to a subnet mask that allows for 2^(32-22) = 1,024 IP addresses within the network. In a /22 network, the first 22 bits of the IP address are used for the network portion, while the remaining 10 bits are used for host addresses. This means that it can accommodate 1,022 usable host addresses (after accounting for the network and broadcast addresses). Typically, a /22 subnet is used in medium-sized networks requiring a moderate number of IP addresses.

A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.
When applying IPv4 addresses to router interfaces on a network, you would manually configure predictable addresses. For example, the lowest or highest address of the local subnet, on each particular router interface.
Private IP addresses
A network administrator can find configuration information, including computer names and IP addresses, in several places. This information is typically stored in the network's DHCP server, which assigns IP addresses dynamically, or in the static IP configuration settings on individual devices. Additionally, network documentation and management tools like network monitoring software can provide an overview of the current network configuration. The command line tools (like ipconfig on Windows or ifconfig on Linux) can also be used to view the IP addresses and hostnames of devices on the network.

MAC addresses are unique identifiers assigned to network interfaces for communications on a local network. They are typically expressed in hexadecimal format and consist of six pairs of digits, separated by colons or hyphens. MAC addresses operate at Layer 2 of the OSI model and are used to facilitate data transfer between devices in a local area network (LAN). Unlike IP addresses, MAC addresses do not change and are tied to the hardware of the device.
