pin_ptr reopened NET-641:
-------------------------
My idea:
public boolean isInRange(int address) {
long addLong = address & UNSIGNED_INT_MASK;
if (inclusiveHostCount) {
return networkLong() <= addLong && addLong <= broadcastLong();
} else {
return networkLong() < addLong && addLong < broadcastLong();
}
}
> SubnetUtils.SubnetInfo.isInRange("0.0.0.0") returns true for CIDR/31, 32
