Mask conversion

Input type

Prefix

Wildcard bits are the inverse of subnet-mask bits. Non-contiguous ACL wildcards are valid in some devices, but cannot be converted to a CIDR prefix.

Results

CIDR prefix: /24
Subnet mask: 255.255.255.0
Wildcard mask: 0.0.0.255
Binary wildcard: 00000000.00000000.00000000.11111111
