After rebooting a computer that you work with remotely you observe that you can no longer ping
it’s IP-address. After physically checking out the computer you see that it is ok, it has just changed
it’s IP-address. What should this behavior tell you?

A.
network interface card (NIC) driver needs to be updated.

B.
DNS server is down.

C.
computer does not have a static IP address.

D.
Ethernet cable is a crossover cable.

Explanation:
Even if a computer has a lease on an IP-address for a period of time and it automatically renews it
when the lease is running out it sometimes happens that the “normal” ip-address is already taken
when it is time to renew the lease, and in that case it will be assigned an other IP-address.
