What is the slash designation for Class A networks?

  1. /8

  2. /16

  3. /24

  4. /32

The correct answer is: /8

Class A networks have a default subnet mask of 255.0.0.0, which equates to a /8 designation. This means that the first 8 bits of the IP address are reserved for the network portion, while the remaining bits are available for host addresses. The other options, /16, /24, and /32, are used for Class B, Class C, and Class D networks respectively. Therefore, they are not the correct slash designations for Class A networks.
