What does a successful ping to a web server indicate?

Internet connectivity is established
The DNS server is properly configured
The server is operational
All of the above

The correct answer is: All of the above

A successful ping to a web server indicates that the server is operational, meaning it is up and responding to requests. When a ping is sent, it uses the Internet Control Message Protocol (ICMP) to send echo request packets to the target server, which in turn sends back echo reply packets if it is functional. This confirms that the server can receive and respond to data packets, indicating its operational status. Additionally, for the ping to reach the server and come back successfully, it implies that internet connectivity is established. One can assume that the network path from the client to the server is functional, thereby confirming effective internet connectivity. Furthermore, successful resolution of the web server's IP address (which is generally required before sending a ping request) indicates that the DNS server is properly configured. During this process, if there is an issue with DNS resolution, the ping cannot reach the server, thereby suggesting that the DNS may not be functioning correctly. Therefore, a successful ping encompasses all these aspects: the server is operational, internet connectivity is established, and the DNS server is configured properly. This combination of confirmations justifies the conclusion that all the mentioned factors contribute to the successful ping outcome.
