Questions & Step-by-Step Solutions
In IP addressing, what does the subnet mask 255.255.255.0 indicate?
Step 1: Understand what an IP address is. It is a unique number assigned to each device on a network.
Step 2: Learn about subnet masks. A subnet mask helps to divide the IP address into two parts: the network part and the host part.
Step 3: Recognize that the subnet mask 255.255.255.0 is written in decimal format. It can also be represented in binary.
Step 4: Convert 255.255.255.0 to binary. It becomes 11111111.11111111.11111111.00000000.
Step 5: Count the number of '1's in the binary subnet mask. There are 24 '1's.
Step 6: Understand that a subnet mask of 255.255.255.0 indicates a Class C network, which typically has 24 bits for the network and 8 bits for the host.
Step 7: Calculate the total number of IP addresses. With 8 bits for hosts, you can have 2^8 = 256 addresses.
Step 8: Realize that out of these 256 addresses, 2 are reserved (one for the network and one for the broadcast), leaving 254 usable IP addresses.
