DATA COMMUNICATION
1. What is the IP address of your host? What is the IP address of the destination
host?
The host IP address is 192.168.43.247 and the destination IP address is 143.89.44.246.
2. Why is it that an ICMP packet does not have source and destination port
numbers?
ICMP is a protocol which is designed so that the communication can take place in
between the routers and the hosts with the information gained from the network-layer.
However, this does not interfere with the processes in the application layer. Hence, the ICMP
packet does not have source and destination port numbers.

3. Examine one of the ping request packets sent by your host. What are the
ICMP type and code numbers? What other fields does this ICMP packet have?
How many bytes are the checksum, sequence number and identifier fields?
The ICMP type is 8 and the code number is 0. The other fields that the ICMP packet
have are checksum, checksum status, identifier (BE), identifier (LE), sequence number (BE),
sequence number (LE) and data. The checksum is 2 bytes, sequence number is 2 bytes and an
identifier field is of 2 bytes.
