- In a class A subnet, we know the IP address of one of the hosts and the subnet mask as given below: IP Address: 25.34.12.56 Subnet mask: 255.255.0.0 What is the first address (subnet address)? What is the last address?Q7. Suppose we have the following IP addresses for two different organizations, we have to create 5 networks having 30 hosts in it. Find first sub network ID, Fist address, Last address and Braodcast for each of the following given addresses.a. 17.23.120.8b. 252.5.15.111Suppose you have been given this classful IP address 130.1.1.8. You want to create a network of 1024 (assignable) IP addresses, what will be the length of network and host part?
- 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.Suppose a user has a webserver running at a machine with the name nadir.edu.net.pk and IP address 10.10.10.10. The authoritative DNS address for this web server is with the name dns.nadir.edu.net.pk and with IP address 11.11.11.11. Write all the steps involved in retrieving the IP address of nadir.edu.net.pkQ2 Using this IP address 150.150.55.20 solve the following questions- Which Class this IP related to?- Suppose you use the following subnet mask 255.255.252.0 ,What is the number of hosts exist within a subnet?- What should you do to make each subnet have at least 200 hosts?
- Take the Class A address 10.0.0.0 and answer the following questions by typing those answers at the end of each question: What is the default subnet mask of a Class A IPv4 address? What is the first usable IP address of this “not-subnetted” network? What is the last usable IP address of this “not-subnetted” network? What is the broadcast address of this “not-subnetted” network? How many total hosts are allowed on this “not-subnetted” network? Let’s split this network into 4 subnets What is the new subnet mask? What is the first subnet address of your newly subnetted address? What is the first usable IP address of your newly subnetted address? What is the last usable IP address of your newly subnetted address? What is the broadcast address of your newly subnetted address? How many usable hosts on this subnet? Fill in the following information for the second, third, and fourth new subnets: Network (subnet) address Usable host range BroadcastSuppose a user has a webserver running at a machine with the name www.nadir.edu.net.pk and IP address 10.10.10.10. The authoritative dns address for this web server is with the name dns.nadir.edu.net.pk and with IP address 11.11.11.11. a. Write all the steps involved in inserting this webserver name in the DNS hierarchy. b. Write all the steps involved in retrieving the IP address of www.nadir.edu.net.pkWhat 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.
- Assume that Computer A, which is connected through an Ethernet cable to the Switch S1, is just powered on.
