- so given two printer, one of IP address is 200.23.16.202 and subnet mask is 255.255.255.224, and other one IP address is 200.23.16.170 and subnet mask is 255.255.255.224. Suppose the network that hosts the above printer is re-configured with other networks in the building. After re-configuration, the printer's IP address would remain the same but its network is changed with a new subnet mask, which is changed to 255.255.255.128. This means, even the printer's IP address looks the same, its network ID and host ID are different from those before re-configuration. Find the new network ID and host ID of this printer. You must write both in the standard dot-decimal format without attaching the subnet mask.Let's pretend a computer sends a packet to another computer on the Internet at the network layer. A problem has occurred with the packet's logical destination address. Where should I send the package? When this occurs, how will the original computer find out?consider 3 hosts (A , B and C) where A is running 3-TCP process, B has 1-TCP process and C is running 2-UDP process all process are trying to connect to a web server to download a file . How many new socket(s) will be created at the server side? Explain why?
- Consider a IP address 201.24.58.69 in classful address, if the number of 1's in directed broadcast address is a and number of 1's in network ID, of the given IP address is b, value of a + b.Assume that a national ISP is assigned an IPv4 block which starts with 132.56.40.0/16 and creates 4 subblocks to be assigned to 4 local ISPs. What will be the /n value for local ISPs?Consider the following non-default subnet masks: (a) 255.255.248.0, (b) 255.128.0.0 . To which IP address class do they pertain?Write down the following in CIDR notation: (a) IP: 150.160.170.180, Subnet Mask:255.255.224.0; (b) IP: 75.80.85.90, Subnet Mask: 255.252.0.0 Three stations A, B, C and D are connected to a common Ethernet hub. Their IPaddresses and subnet mask are respectively: 200.100.50.67, 255.255.255.252;200.100.50.7, 255.255.255.248; 200.100.50.138, 255.255.255.240 and 200.100.50.1,255.255.255.254. Determine which among these stations can communicate with eachother. You need to show all detailed workings.
- Let's imagine that a computer on the Internet transmits a packet to another computer at the network layer. The logical destination address of the packet has encountered an issue. What address should I use for the package? How will the original computer know when this happens?Let’s consider you have a Class C IP address 204.15.5.0/24. You have to determine whether it is possible to createfollowing network with the given IP address? If yes, what could be the possible ranges of IP addresses for thesubnetworks? Let’s consider the above network. If you are using VLSM /CIDR, determine what subnet mask numbers allow therequired number of hosts.QUESTION 21 It is possible for two UDP segments to be sent from the same socket with source port 5723 at a server to two different clients. True False QUESTION 22 The acronym API in this textbook stands for “Application programming interface”. True False
- Assume that a computer transmits a packet to another computer on the Internet at the network layer. The packet's logical destination address is broken. Where does the package go? What is the best way to alert the source computer?1. Encode the following message in base64 01010111 00001111 11110000 2. The following is a dump (contents) of a UDP header in hexadecimal format 0045DF0000580000 a. what is the source port number? b. what is the destination port number? c. what is the total length of the user datagram? d. what is the length of the data? e. what is the application layer protocol? 3.Why does the network-layer protocol need to provide packetizing service to the transport layer? 4. List four types of delays in a packet-switch network.Consider a short, 10-meter link, over which a sender can transmit at a rate of 150 bits/sec in both directions. Suppose that packets containing data are 100,000 bits long, and packets containing only control (e.g., ACK or handshaking) are 200 bits long. Assume that N parallel connections each get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 100 Kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender. Would parallel downloads via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Do you expect significant gains over the non-persistent case? Justify and explain your answer
