1. How does ping work? Use Wikipedia or another resource to write a brief description of how ping works. 2. Use Wikipedia or another resource to write a brief description of the Internet Control Message Protocol (ICMP) and its use. 3. Ping the website of your university. Show the output. What is the average round-trip time? (If your university is locked down, i.e. does not respond to ping queries, try your ISP’s website.) 3. Ping the website of your university. Show the output. What is the average round-trip time? (If your university is locked down, i.e. does not respond to ping queries, try your ISP’s website.) 4. Ping the website of a university in a neighboring city or town. Show the output. What is the average round-trip time? (Again, if the website is locked down, try the website of a company in another state.) 5. Ping the website of a company, university, or organization located abroad. Show the output. What is the average round-trip time? 6. You wake up one day to find that you are unable to connect to the Internet from home. You make some calls to your friends and neighbors and find that they have no issues connecting to the Internet. You conclude that the fault is within your home. As seen in Figure 4.21, there are two networking components within your home—your computer and your home router. As seen in Figure 4.22, the IP address of the home router is the IP address of the default gateway in your ipconfig output, and home routers typically respond to ping requests. How can you use ping to determine whether the network connectivity problem is at the home router or at your computer? 6.

Solution

Ping is the network diagnostic tool that is used to check
if a host in network is alive and responding.Ping is uses ICMP
messages,more perticularly querry message.
They send request messages to a target network address at periodic intervals and
measure the time taken for a response message to arrive,

Example

ping -n 5 -1 1500 www.abcd.com
