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.
There is a routing table in the figure on a router. If packets with the following destination IP addresses arrive at the router, where are they routed? a) 198.52.61.10b) 198.53.40.201c) 198.52.60.89d) 198.52.63.113 Show your work and reasoning for each option.
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.
A router running Classless Interdomain Routing (CIDR) has the following entries in its routing table: Address/mask Next hop 135.46.56.0/22 Interface 0 135.46.60.0/22 Interface 1 192.53.40.0/23 Router 2 Default Router 3 How does a CIDR router work to route the packets it received? For each of the following IP addresses, what will the router do if a packet with that address arrives? (a) 135.46.63.10 (b) 135.46.58.16 (c) 135.46.52.2 (d) 192.53.40.7 (e) 192.53.56.7
A CIDR router contains in its routing table the mask M 255.255.224.0 and the base address BA÷198.57.160.0 of the corresponding attached network. A packet with the destination address P 198.57.223.148 arrives at the router. Will the router forward this packet to the attached network? Explain

What is the maximum number of hosts that can be accommodated in a subnet with a subnet mask of 255.255.255.224?
A simple CIDR routing table is shown in Figure 1. For each of the destination IP addresses below, indicate which entry in the table it matches. Indicating none if no routing entry can be matched (hint: given an IP packet, the router will check whether there is a routing entry which can be used to route this packet, by checking the destination IP address in the packet with each routing entry: based on the subnet mask of each routing entry, it can extract the network ID and compare it with each routing entry; if there are a few routing entries which can match, the entry with the longest subnet mask wins). Address Mask Output Port 10.19.0.0/16 1 10.19.128/17 2 10.19.192/18 3 10.19.192/19 4 0.0.0.0/1 5 141.219.2.10 10.10.10.10 10.19.86.141 10.19.193.6 10.19.255.86 10.19.192.18
What is the purpose of an IP address mask? Suppose an IP address is identified as 200.60.40.88/24. What is the network address in this case? What is the host address? How many hosts can this network address support? Repeat this exercise for the IP address 222.66.44.80/26.
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.
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
