Networks: Ping

A user can ping the IP address of a specific sever but she cannot ping the server via its domain name.
What is not working properly?
1. The DHCP server
2. The network card
3. >>The DNS server
4. The hub

Explanation : When you can reach a computer by its IP address but not by its domain name, it points to a problem with the Domain Name Service (DNS). DNS servers look up requests for domain names and translate them into IP addresses.

Dynamic Host Configuration (DHCP) servers automate IP addressing and TCP/IP configuration. They assign IP addresses to computers that are configured to receive their TCP/IP configuration automatically. A problem with the DHCP server would become apparent because computers would not receive IP addresses and would then use Automatic Private IP Addressing (APIPA) to assign themselves an address.

If the hub or the network card were not working properly, the user would not be able to ping the server at all.
