No, 255.255.255.0 is not a Class C address; it's the default subnet mask for a Class C network. Class C addresses themselves have a first octet between 192 and 223.
Understanding Class C Networks
Class C networks are a specific type of IP network, distinguished by their address range and typical usage. Let's break it down:
Key Features of Class C Networks
| Feature | Description |
|---|---|
| First Octet Range | 192 to 223 |
| Default Subnet Mask | 255.255.255.0 |
| Network Bits | 24 bits |
| Host Bits | 8 bits |
Subnet Masks
Subnet masks are crucial in defining the structure of a network. They separate the network address from the host address within an IP address.
- A subnet mask of 255.255.255.0 signifies that the first three octets (24 bits) of an IP address are used for the network address and the last octet (8 bits) are for host addresses.
Example
- The reference indicates that an IP address like 192.168.123.132 is a valid Class C IP address.
- When this Class C address uses the 255.255.255.0 subnet mask, the network part is 192.168.123 and the host part is 132.
Clarification
The question can be rephrased as: "Is the subnet mask 255.255.255.0 the default subnet mask for a Class C network?" The answer to this question is yes. As the reference clearly states, Class C networks use a default subnet mask of 255.255.255.0. It is important to note that a subnet mask is not the same as an IP address.
