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.
DHCP
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to network devices, simplifying network administration and reducing configuration errors. It also provides additional network configuration information, such as DNS servers and default gateways, to help devices communicate efficiently in a network.
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.
Dynamic Host Configuration Protocol (DHCP) A protocol that provides a means to dynamically allocate IP addresses to computers on a local area network. The system administrator assigns a range of IP addresses to DHCP and each client computer on the LAN has its TCP/IP software configured to request an IP address from the DHCP server. The request and grant process uses a lease concept with a controllable time period.
distribution
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.
It is what... DHCP is designed to automatically distributed IP addresses to connected to the same network devices.
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.
