- 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.Consider the LAN below consisting of 12 computers (A-L) connected by two Ethernet bridges. At t=0 the bridging table entries for both bridges are empty. At t = 1, node L sends to node E, and node E replies immediately (well before the next time step). What are the (MAC address, interface) entries in the bridging tables right after these transmissions? Note: interface = port number a) Left-hand-side bridge: (L,15), (E, 8). Right-hand-side bridge: (L,7), (E, 5). b) Left-hand-side bridge: (L,8), (E, 8). Right-hand-side bridge: (L,7), (E, 7). c) Left-hand-side bridge: (L,15), (E,5). Right-hand-side bridge: (L,7), (E, 8). d) Left-hand-side bridge: (L,8), (E,8). Right-hand-side bridge: (L,7), (E, 7).Suppose that a Web server runs in Host C on port 80. Suppose this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. Are all of the requests being sent through the same socket at Host C? If they are being passed through different sockets, do both of the sockets have port 80? Discuss and explain.
- Addresses starting with fe80 are called link-local IPv6 addresses. True or falsethe UDP server described needed only one socket, whereas the TCP server needed two sockets. Why? If the TCP server were to support n simultaneous connections, each from a different client host, how many sockets would the TCP server need?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 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.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?A network configuration of a modem is given as following:LTE interface IP = 77.110.156.22 MASK 255.255.252.0Default GATEWAY = 77.110.156.1Masquerade NAT, and DNS address = 1.1.1.1Local IP setup: 192.168.128.1 MASK 255.255.255.0And, ip route 192.168.128.0 255.255.252.0 192.168.128.254 Devices numbered R1, R2, R4, R5 are routers. PC is a computer.Image of network with interface names such as f1/0 are added. You must use only static IP addreses and static IP routes to configure the network and make PC able to connect (ping) to Modem.
- Suppose that a Web server runs in Host C on port 80 . Suppose also that this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. a) Are all of the requests being sent to the same port number at Host C? b) Will the client use port 80 in its local machine to communicate with the server? c) How does the server differentiate between the two requests?Consider the Host Aand Host B TCP link. Assume that the TCP segments that fly from host Ato host B have source port x and destination port y. What are the source and destination port numbers of Host B to Host A segments?Consider incoming TCP and UDP segments arriving at a server, and suppose that we see that 100 different destination port numbers are being used. The server acts only as a server (that is, in the socket sense, it does not initiate communication with any other computers as a client; it only responds to incoming segments). Describe the number of sockets being used at this server and justify your answer
