CCNA – DHCP Questions
Note: If you are not sure about DHCP, please read our DHCP tutorial.
Network or subnetwork IP address (for example 184.108.40.206/8 or 220.127.116.11/16) and broadcast address (for example 18.104.22.168/24) should never be assignable to hosts. When try to assign these addresses to hosts, you will receive an error message saying that they can’t be assignable.
An address conflict occurs when two hosts use the same IP address. During address assignment, DHCP checks for conflicts using ping and gratuitous ARP. If a conflict is detected, the address is removed from the pool. The address will not be assigned until the administrator resolves the conflict.
