  - isInRange
```
public boolean isInRange(java.lang.String address)
```
    Returns true if the parameter address is in the range of usable endpoint addresses for this subnet. This excludes the network and broadcast adresses.
    
    参数:
    address - A dot-delimited IPv4 address, e.g. "192.168.0.1"
    
    返回:
    True if in range, false otherwise
  - isInRange
```
public boolean isInRange(int address)
```
    参数:
    address - the address to check
    
    返回:
    true if it is in range

  - getBroadcastAddress
```
public java.lang.String getBroadcastAddress()
```
  - getNetworkAddress
```
public java.lang.String getNetworkAddress()

```
  - getAddress
```
public java.lang.String getAddress()
```
  - getLowAddress
```
public java.lang.String getLowAddress()
```
    Return the low address as a dotted IP address. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.
    
    返回:
    the IP address in dotted format, may be "0.0.0.0" if there is no valid address
  - getHighAddress
```
public java.lang.String getHighAddress()
```
    Return the high address as a dotted IP address. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.
    
    返回:
    the IP address in dotted format, may be "0.0.0.0" if there is no valid address
  - getAddressCountLong
```
public long getAddressCountLong()
```
    Get the count of available addresses. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.
    
    返回:
    the count of addresses, may be zero.
    从以下版本开始:

```
  - getCidrSignature
```
public java.lang.String getCidrSignature()
```
  - getAddressCount
```
public int getAddressCount()
```
    Get the count of available addresses. Will be zero for CIDR/31 and CIDR/32 if the inclusive flag is false.
    
    返回:
    the count of addresses, may be zero.
    
    抛出:
    
    java.lang.RuntimeException - if the correct count is greater than Integer.MAX_VALUE
  - getAllAddresses
