Soalan subneting

  1. 1. Question 1: Given the IP address block of 192.168.30.0/24, design an IP addressing scheme that satisfiesthe following requirements:■ Subnet A has 100 hosts.■ Subnet B has 50 hosts.■ Subnet zero is used.■ Create the smallest possible subnets that satisfy therequirements for hosts.■ No subnet calculators may be used. 1) Subnet Calculations for Subnet A is provided.Subnet Specification CalculationNumber of bits in the subnet 25New IP mask (binary) 1111 1111. 1111 1111 . 1111 1111 . 1000 0000New IP mask (decimal) 255.255.255.128Maximum number of usable subnets 2(including the 0 subnet)Number of IP per subnet 128Number of usable hosts per subnet 126IP subnetwork address 192.168.30.0First IP host address 192.168.30.1Last IP host address 192.168.30.126Broadcast IP address 192.168.30.127Next subnet IP address 192.168.30.128Next subnet IP host address 192.168.30.129Next subnet IP host last address 192.168.30.254 2) What is the Subnet Calculations for Subnet BSubnet Specification CalculationNumber of bits in the subnet 26New IP mask (binary) 1111 1111. 1111 1111 . 1111 1111 . 1100 0000New IP mask (decimal) 255.255.255.192Maximum number of usable subnets 4(including the 0 subnet)Number of IP per subnet 64Number of usable hosts per subnet 62IP subnetwork address 192.168.30.128First IP host address 192.168.30.129Last IP host address 192.168.30.158Broadcast IP address 192.168.30.159Next subnet IP address 192.168.30.160Next subnet IP host address 192.168.30.161Next subnet IP host last address 192.168.30.174
