- Registration Number: 193046 Consider a network with 3 hosts and a NAT router. Suppose that the network address of the home network is 192.168.NNN/24, where NNN are the last 3 digits of your Reg#. For example, if your Reg# is BSE193046, NNN = 046 and therefore the network address wil be 192168.46/24. (If NNN>255, consider NNN=254) (a) Assign any public IP address to NAT router’s outgoing interface. (b) Assign IP addresses to all 3 hosts and local interface of the NAT router in the home network. (UDP Echo ApplicationA UDP Echo program is a simple network application that demonstrates the basicprinciples of UDP communication. In this program, a server listens for incoming UDPpackets from clients, and when it receives a packet, it echoes (sends back) the samepacket to the client. The client sends a message to the server, and the server returns thesame message. It's often used for testing network connectivity and understanding thefundamentals of UDP communication. (Answer the following question using python) Implement both the server and client components of this UDP Echo program whileadhering to the features outlined below. Please ensure that your implementation followsgood coding practices and provides clear prompts and feedback to the user, making ituser-friendly and robust. Please refer to the class example to guide your implementation. 1) UDP Echo Server Receiving and Displaying Messages: The UDP Echo server should be able toreceive messages sent by clients. For each…Consider a home network connected to the Internet through a single home router that supports the Network Address Translation (NAT) protocol. The ISP is only providing a single public IP address to the owner of this network (82.7.30.73). Let us assume that one of the connected home devices with IP address 192.168.0.1 has an open connection from source port 30000 to a web server with IP address 172.217.169.4. The source IP and port of the incoming TCP segments that the web server sees could be: 192.168.0.1, 30000 82.7.30.73, 5555 192.168.0.1, 5555 172.217.169.4, 80
- An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?Consider the following network: Router1 10.0.0.1 00:00:00:00:01 X Switch 1 10.0.0.0/24 Alice 10.0.0.2 00:00:00:00:02 Bob 10.0.0.3 00:00:00:00:03 Charlie 10.0.1.2 00:00:00:00:05 (A) Charlie sends message with source IP 10.0.0.2 to destination IP 10.0.0.3 (B) Bob sends message with source IP 10.0.0.2 to destination 10.0.1.3.
