Which wildcard mask is equivalent to "any"?

Answer options

• A. 0.0.0.0
• B. 11111111
• C. 00000000
• D. 255.255.255.255

Correct answer: A

Explanation

The correct answer is A, 0.0.0.0, as this wildcard mask indicates that any IP address is acceptable. Option B, 11111111, does not represent a valid wildcard mask format, while option C, 00000000, is not used for matching any address. Option D, 255.255.255.255, represents a wildcard mask that matches no addresses.
