What Is Wildcard Mask?

Answer»

Wildcard MASK is used with ACL to specify an individual hosts, a network, or a range of network. WHENEVER a zero is present, it indicates that octet in the address must match the corresponding REFERENCE exactly. Whenever a 255 is present, it indicates those octets NEED not to be evaluated.

Wildcard Mask is completely opposite to subnet mask.

Example:- For /24

  • Subnet Mask - 255.255.255.0
  • Wildcard Mask - 0.0.0.255
