IP-Subnet-Mask numbers IP mask numbers are used to divide internet addresses into blocks called subnets. The mask number represents the number of 1s in the binary of the address that is ’masked" against the address so that it ignores the last bits which are for the group of IP addresses in the masked address. The first address of a subnet block (all 0s) is called the network address or network ID. The last address (all 1s) is the broadcast address of the network. Typically the network address

1) Identify the three IP address classes‚ the default subnet mask used with each‚ and the number of hosts for each. The three IP address classes are class A‚ class B‚ and class C. Default subnet mask for class A = 255.0.0.0 Default subnet mask for class B = 255.255.0.0 Default subnet mask for class C = 255.255.255.0 The number of hosts that class A can have is 16‚777‚214 The number of hosts that class B can have is 65‚534 The number of hosts that class C can have is 254 2) What is the subnet
