Suppose that an organization has taken a private class B network 172.16.0.0/16 and broken it multiple subnets using variable length subnet masks. If a host has IP address 172.16.40.10 and mask of 255.255.240.0, The subnet to which the host belongs is in dotted decimal form. The broadcast address for this subnet in dotted decimal form is (Note: not 255.255.255.255). The number of of hosts can this subnet accommodate is (do not include re addresses). The first (lowest) IP address that can be assigned to a host in this subnet is decimal form.

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.
P11. Consider a subnet with prefix 128.119.40.128/26. Give an example of one IP address (of form xxx.xxx.xxx.xxx) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 128.119.40.64/26. Suppose it wants to create four subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form a.b.c.d/x) for the four subnets?
Q3: Assume the given class C IP Address, 192.168.0.X, where; X is the last two digits of your arid number (For example a student having 19-arid-121 will use ASCII of 21 as X . Apply subnetting of 3 bits and write about: a. Network and Broadcast IP of the subnet in which this IP 192.168.0.X belongs to b. First and last valid IP of the subnet in which this IP 192.168.0.X belongs to. c. Sub-net mask of this IP after subnetting.
Consider a web page whose base file is of size S1 = 10 KB. Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? ”Pipelined” means requests for multiple objects can be sent back-to-back on the same connection.d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.
For example, let say that your Network 1 needs 30 hosts and you are in a class C network, you would start with 192.168.0.1 till 192.168.0.32 because the closest you can get to 30 that is more is 32 (2exp5) so my begin address would be 192.168.0.1, end address would be 192.168.0.32 (not 192.168.0.30 because we only need 30 hosts) and subnet mask would be 255.255.255.224. The next range will start at 192.168.0.33!!! Use the example to answer: We are going to use the private range for a class A network. What is its standard subnet mask? A) Network 1 needs 250 hosts B) Network 2 needs 230 hosts

. Consider a network with prefix 182.168.56.128/26. Give an example of one IP address (of form xxx.xxx.xxx.xxx) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 170.168.56.64/26. Suppose it wants to create four subnets from this block, with each block having the same number of IP addresses.

Assume that a large number of consecutive IP addresses are available starting at 198.16.32.0 and suppose that two organizations, A, B, C, and D, request 1000, 3000, 2000, and 4500 addresses, respectively, in that order. For each of these, give the first possible IP address within the assigned subnet, the last possible IP address within the assigned subnet, and the subnet representation in slash notation (w.x.y.z/s). In the imagine I have the answers but I am very confused on how to get them. Specially after A and B I do not undertand how the initial address of C is 198.16.64.0 how did that 64 happen??? Please explain all in detail. Thank you!
Using packet tracer, implement a network that has the following components: 1- At least five routers 2- At least 7 subnets 3- At least 12 PCs 4- At least 4 switches 5- Use RIP routing protocol To assign IP addresses of the routers and PCs, use the IP address from your ID as follows Assume your id is 118zyxw, Consider the numbers z, y, x and w as deciemal You have the subnet 118.0.0.0/24 If your ID is 1181234 then the IP is 118.0.0.0/24 Use this subnet to get at least 7 subnets.
Suppose a user from Taman Jatt Kata Kinabalu is working from a machine at home with IP address 10. 0. 0.10 on a local network attached to a router connected to the Internet The user requests a web page through a Web browser.

In this programming assignment, you will implement a decentralized peer-to-peer network architec-ture (P2P), including the basic implementation of the BitTorrent protocol (BTP). General P2P architec-tures can be classified into centralized and decentralized, In P2P centralized architectures, new peers senda request to the Traker (normally done via HTTP) requesting a list containing all the IP addresses ofthe peers that are already connected to the P2P network sharing the same file. The tracker then, replieswith a response containing such list. In P2P decentralized architecture, each peer is also a Traker, and itcan share only limited resources because it only sees the partial network. On the other hand, P2P decen-tralized networks avoid single point of failure since they do not depend of centralized trackers. Examplesof P2P applications that are/were implementing centralizing architectures are Nasper, the Berkeley OpenNetwork Infrastructure (BOINC) and some versions of BitTorrent.…
49- An organization currently requires 40 hosts for its sales department. Given the IP Address 194.12.1.0 /24, design an optimal address scheme usingTradition Subnetting method, which will enable the connection of the sales department’s 40 hosts in one subnet and uses the remaining subnets for other departments’ hosts in the future. What will be the last host address of 4th subnet? Select one: A. 194.12.1.254 B. 194.12.1.192 C. 194.12.1.253 D. 194.12.1.255
