Within a classful addressing subnet mask, the 32 bits indicate that corresponding bits in an IPv4 address contain network information.
<h3>What is classful IP
addressing?</h3>
IP address is the address or the code of location to reach at a specific location. It is a unique address of 32 bit.
This address is classified in five classes.
- Class A
- Class B
- Class C
- Class D
- Class E
These class are necessary to obtained the bits for network ID.
Thus, within a classful addressing subnet mask, the 32 bits indicate that corresponding bits in an IPv4 address contain network information.
