Description

I checked this website for CIDR notation to ensure it was accurrate:

https://account.arin.net/public/cidrCalculator

I utilized the IP address 10.65.0.151 and the prefix of 32.  From that website, it shows the only address available was 10.65.0.151.

I instantiated SubnetUtils using CIDR notation "10.65.0.151/32".  I expected true to be returned when using the SubnetUtils.isInRange(String address) for "10.65.0.151".  However it does not return true, and it will only return true using prefix "30".

I attached a crude unit test to demonstrate the issue.
