After rebooting a computer that you work with remotely you observe that you can no longer ping its IP-address. After physically checking out the computer you see that it is ok, it has just changed its 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 another IP-address.
