Basically, any device that needs to communicate with another device on an IP network will require an IP address. so, each PC and router will need an address, along with anything else per above: a switch, a server, and IP phone, etc.
dhcp
An IP pool is a collection of IP addresses that are available for assignment to devices on a network, typically managed by a DHCP (Dynamic Host Configuration Protocol) server. This pool allows for efficient allocation and management of IP addresses, ensuring that devices can connect to the network without conflicts. IP pools can be dynamic, where addresses are assigned temporarily, or static, where specific addresses are reserved for particular devices. They are essential for managing network resources, especially in environments with numerous devices.
A DHCP (Dynamic Host Configuration Protocol) range refers to the set of IP addresses that a DHCP server can assign to devices on a network. This range is defined by a starting and ending IP address, allowing the server to dynamically allocate addresses to devices as they join the network. The DHCP server manages this range to ensure that IP addresses are assigned efficiently and without conflict, facilitating seamless network connectivity for devices.
The correct answer is switch.
More unique ip addresses, so essentially more devices on the network.
These addresses are not assigned to devices because they have a reserved meaning. All zeroes refers to "this network", and all ones usually is assigned to a broadcast address (all devices).
The DHCP service.
Computers that are connected to each other create a network. These networks are often configured with "public" internet Protocol (IP) addresses -- that is, the devices on the network are "visible" to devices outside the network (from the Internet or another network). Networks can also be configured as "private" -- meaning that devices outside the network cannot "see" or communicate directly to them.
It is what... DHCP is designed to automatically distributed IP addresses to connected to the same network devices.

OUI (Organizationally Unique Identifier) is used in MAC addresses of network devices to identify the manufacturer or vendor of the device. It helps in organizing and managing network traffic, troubleshooting network issues, and ensuring security by identifying the origins of devices connected to the network.
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.
