If the DHCP Server suddenly shuts down, what happens to all the DHCP clients that have obtained IP addresses from the server?
The clients will be able to communicate only by IP address not by hostname.
The clients will be able to continue communicating, but only for a certain period of time.
The clients will lose connectivity immediately among each other.
The clients will be able to communicate only to the Gateway but not between each other.
Explanation
Dynamic allocation is as follows: If the IP address is not reclaimed, the DHCP server will not renew it, therefore the host that wants to continue using the IP needs to periodically reclaiming it to the DHCP server. If DHCP Server looses connectivity or shuts down, the clients will keep the DHCP information for a certain period of time. After the period of time is finished, all clients will lose the IP information assigned by the DHCP Server.
