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 ID of host 86.212.118.145, given a subnet mask of 255.0.0.0? Explain your answer. Subnet ID = 86.0.0.0
The first 8 bits of the host address and set the rest of the numbers in the address to 0. 3)What is the subnet ID of host 192.168.18.145, given a subnet mask of 255.255.255.0? Explain your answer. Subnet ID = 192.168.18.0

Basically just take the last 0 off the subnet mask and put it on the end of the IP address.
