Problem
You are the network administrator for a campus network and immediately after completing a server migration project, you start receiving complaints from network users that they can't reach the Internet. You sit down at a network PC and try to ping the URL of a well-known website, which fails. You then try to ping the public IP address of the same website, which succeeds.
Consider and evaluate all the four reasons suggested below and justify whether each of these reasons is the most likely problem or not?
a) IP addresses are set incorrectly on network PCs.
b) Incorrect subnet mask is set on network PCs.
c) DNS settings are incorrect.
d) No gateway address is set on network PCs.
