Almost immediately after a server migration project, employees are complaining that they can't reach the internet. you sit down at a machine and try to ping a well-known website using the host name, which fails. you then try to ping a known public ip address, which succeeds. what is most likely the problem?
a. ip address of each machine is set incorrectly. b. dns settings are incorrect. c. subnet mask is wrong. d. no gateway address is set.

b. DNS settings are incorrect

Explanation:

DNS (Domain Name System) settings help to translate web addresses to their IP addresses. Domain Name System servers help to establish a link between human-readable address (host name) and computer readable address (IP address) trough its network.

If the ping to a IP address works but ping to a host name does not, it means that the system interpreting host names to IP addresses doesn't work properly.

you paid for the subscription lol
