Question: ICMP is a UDP protocol. It's used to ping an address to determine if connection is established between the host and destination addresses. Open

ICMP is a UDP protocol. It's used to ping an address to determine if connection is established between the host and destination addresses.

 
  2. Open Windows command prompt or Mac terminal. What command is used to find out the IP address of your host?
  4. Try one of the ping request packets sent by your host. For example, at the prompt, type ping localhost. How many packets are sent, received, and lost?
  6. Are the resource and destination port numbers associated with the ping request? If not, give reasons why an ICMP packet does not have source and destination port numbers.
  8. When pinging localhost, the approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms. Why 0ms is displayed on this roundtrip?
  10. Examine the the corresponding ping reply packet in your screenshot. What is TTL? What information does it provide?
