IPRange (druid 1.2.26 API)

java.lang.Object
- com.alibaba.druid.support.http.util.IPRange

```
public class IPRange
extends Object
```
This class represents an IP Range, which are represented by an IP address and and a subnet mask. The standards describing modern routing protocols often refer to the extended-network-prefix-length rather than the subnet mask. The prefix length is equal to the number of contiguous one-bits in the traditional subnet mask. This means that specifying the network address 130.5.5.25 with a subnet mask of 255.255.255.0 can also be expressed as 130.5.5.25/24. The prefix-length notation is more compact and easier to understand than writing out the mask in its traditional dotted-decimal format.
