    Am I correct, the wildcard mask = 0.0.15.255

    that would be the correct conversion for /20...the particular IP given will result is the range of 192.21.96.0 - 192.21.111.255

    But that may not be the correct answer for a question...say they were asking you to indicate a range of subnets that would give you 6 subnets.
    For that all you would need is a /21, or 0.0.7.255 wildcard

    you can practice with a wildcard calculator here
