- An ISP is granted a block of addresses starting with 130.100.0.0/16. The ISP needs to distribute these addresses to 4 large companies. Each company requires 1024 IP addresses. Write the address ranges for these companies into the following table with /n notation. Company First address Last address 1 2 4 3.The given IPV6 subnet address is 2001:0DA7:FF00:FAF8: :/64. • Use the above IPV6 address for Subnet 0. • Increment the subnet field by 1 and find the IPV6 address for the remaining subnets. • Write simplified IPV6 address. Subnet IPV6 network address (Write simplified IPV6 address) Number 1 3. Complete the 2 following IPV6 addressing table 3 using IPV6 subnetting. Follow the instructions given below and write the IPV6 address in the table.Using 130.42.0.0/16, I want to create a subnetting scheme that will allow 12 subnets each of which should support up to 500 IP addresses. Given that the number of bits needed for the subnetting scheme, what will be the subnet mask for the subnets?
- • Given the IP address 165.165.8.0/21. We want to divide this networks into 7 subnetworks, such that: • Network 1: 930 hosts • Network 2: 475 hosts • Network 3: 225 hosts • Networks 4, 5, 6, and 7: 60, 57, 56, and 43 hosts respectively. Answer the following questions: 1. The IP address of Network 1 is: 2. The first IP address in Network 2 is: 3. The last IP address in Network 3 is: 4. The subnet mask of network 4 is: 5. The broadcast address of Network 5 is: 6 The mavimum pumber of possible bosts in Network 6 is:For the given IP address "195.10.10.01" write down it's subnet mask.Suppose 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.pk
- Suppose you has IP address 220.254.255.x / 28, conclude the class and analyze the subnetting for finding mask address, number of subnets, addersses range of subnets , and number of hosts at each subnet.Given the following topology of a network, the router Node 3 connects the two subnets together: Nodes 1 and 2 are 'inside' of the subnet neta, Nodes 4 and 5 are 'outside' of neta and Node 3 with a firewall is the gateway of neta. The two networks have the prefix 192.168 as the first two octets in their IP addresses, e.g, Node 1 has IP address 192.168.1.11. eth1: 1.11 eth1: 2.21 1 2 eth1: 1.12 neta eth 1: 1.1 3 eth2: 2.1 netb 4 5 eth1: 2.22 (i) Suppose in the firewall on Node 3 the default policy is ACCEPT. Write packet filtering rules for the following goal. Suppose Node 5 hosts a web server supporting both HTTP and HTTPs. Set rules in Node 3 that prevents Node 2 from browsing any web pages at Node 5. Now change in Node3 the default policy as DROP and write packet filtering rules for the following goal. (ii) Allow all nodes in the subnet neta to browsing HTTP pages hosted at Node 5. (iii) Allow hosts in netb to SSH into Nodel.Download delays for 100 objects (HTTP 1.1 with browser caching). Consider an HTTP 1.1 client and server. The RTT delay between the client and server is 2 seconds. Suppose the time a server needs to transmit an object into its outgoing link is 3 seconds, as shown below for the first of these 100 requests. initiate TCP connection RTT request file RTT file received time You can assume that any other HTTP message not containing an object sent by the client and server has a negligible (zero) transmission time. Suppose the client makes 100 requests, one after the other, waiting for a reply to a request before sending the next request. 352 secs Using HTTP 1.1, how much time elapses between the client transmitting the first request, and the receipt of the last requested object, assuming the client uses the IF- MODIFIED-SINCE header line, and 50% of the objects requested have not changed since the client downloaded them (before these 100 downloads are performed)? 350 secs 252 secs time to…
- VLSM Create a IP Address scheme using VLSM. You are told to create the following 8 subnets using 10.10.0.0/22. 8. Network H has 59 hosts Complete all the fields in the following table. Make sure to show your work. Network Subnet Netmask CIDR Broadcast Address A B C D E 1. Network A has 50 hosts 2. Network B has 90 hosts 3. Network C has 36 hosts 4. Network D has 190 hosts 5. Network E has 15 hosts 6. Network F has 20 hosts 7. Network G has 100 hosts FGH Number of HostsConsider a home network connected to the Internet through a single home router that supports the Network Address Translation (NAT) protocol. The ISP is only providing a single public IP address to the owner of this network (82.7.30.73). Let us assume that one of the connected home devices with IP address 192.168.0.1 has an open connection from source port 30000 to a web server with IP address 172.217.169.4. The source IP and port of the incoming TCP segments that the web server sees could be: 192.168.0.1, 30000 82.7.30.73, 5555 192.168.0.1, 5555 172.217.169.4, 80An ISP is granted a block of addresses starting with 150.80.0.0/14. The ISP wants to distribute these blocks to customers as follows: A- the first group has 50 customers, each needs 1024 IP addresses. B- the second group has 40 customers, each needs 512 IP addresses C- the third group has 64 customers, each needs 16 IP addresses So, Design all the subnets? And find the amount of available IPs after all allocations.
