Question G.Design 16 subnets for a company with the site address 189.47.217.0. a. What is the network mask? b. What is the subnet mask? c. How many hosts are on each subnet? d. What is the address of the 4th subnet (no partial credit)? Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line
Question 1: Create subnetworks for the following given requirements (IPV4 addresses). 191.148.1.0/24 – Create VLSM scheme for two subnets, Subnet A requires 30 hosts and Subnet B needs 10. 157.149.30.0/24 – Create VLSM scheme for two subnets, Subnet A requires 5 hosts and Subnet B needs 2 hosts Question 2: Research Security issues in IoT (Internet of Things) (one-page font size should be 12 and font style Times New Roman, line spacing single)
q no 5: In the above network diagram, IP and MAC addresses are given for network nodes. Suppose Host1 (Shahid) sends a datagram to Host2 (Khalid). What IP and MAC addresses (source and destination) will be written in IP and Data link layer headers respectively, for the following intermediate points from Host1 to Host2? Host1 to Router1 (R1) Router1 to Router2 (R2) Router2 to Host2
If the answer is copy from existing solution or internet I will surely downvote Dont answer if dont have accurate knowledge I will surely downvote sure if it is wrong or incorrect or alreadu existing solution. Answer only if have accurate knowledge. Host A sends a UDP datagram containing 8880 bytes of user data to host B over an Ethernet LAN.Ethernet frames may carry data up to 1500 bytes (i.e. MTU = 1500 bytes).Size of UDP header is 8 bytes and size of IP header is 20 bytes.There is no option field in IP header.How may total number of IP fragments will be transmitted and what will be the contents of offset field in the last fragment?
This is Networking subject, Fixed length subnet mask (FLSM) Subnetting in IPv4 Network design problem: Given the class b network of 172.30.0.0/16, subnet the network in order to create the network in the figure below with host requirements shown by preparing a complete ipv4 address summary table. Solution: a. Required subnets b. Number of subnets c. Available hosts per subnets d. Network increment (INC) e. New prefix length and subnet mask address f. IPv4 Address summary table
Can someone please explain to me ? ASAP??!! 7. Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three links, of rates R1 = 2 Mbps, R2 = 2 Mbps, and R3 = 4 Mbps. a. Assuming no other traffic in the network, what is the throughput for the file transfer? (5 Points) b. Suppose the file is 4 million bytes. Dividing the file size by the throughput, roughly how long will it take to transfer the file to Host B?
True Or False 1. The acronym API in this textbook stands for “Application Programming for Internet. 2. DSL bandwidth is shared. 3. Suppose 10 connections traverse the same link of rate 1 Gbps. Suppose that the client access links all have rate 5 Mbps. Then the maximum throughput for each connection is 100 Mbps.
Assign network addresses to each of these six subnets,with the following constraints: All addresses must be allocated from 212.10.8/23; Subnets A, B, and C should have enough addresses to support 120, 240, and 120 interfaces respectively. Of course, subnets D, E, and F should each be able to support two interfaces. For each subnet, the assignment should take the form of a.b.c.d/x or a.b.c.d/x - e.f.g.h/y. ----- Using your answer to the previous part, provide the forwarding tables (using longest prefix matching) for each of the three routers. You may use label R1A to denote the interface on router R1 that is part of subnet A and so on.
