IPv4AddressSegment

java.lang.Object
- inet.ipaddr.format.IPAddressDivision
- - inet.ipaddr.IPAddressSegment
  - - inet.ipaddr.ipv4.IPv4AddressSegment

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<IPAddressDivision>
```
public class IPv4AddressSegment
extends IPAddressSegment
```
This represents a segment of an IP address. For IPv4, segments are 1 byte. For IPv6, they are two bytes. Like String and Integer and various others basic objects, segments are immutable, which also makes them thread-safe.

public IPv4AddressSegment(int value)
```
    Constructs a segment of an IPv4 address with the given value.
    
    Parameters:
    
    value - the value of the segment
  - IPv4AddressSegment
```
public IPv4AddressSegment(int value,
                          java.lang.Integer segmentPrefixLength)
```
    Constructs a segment of an IPv4 address.
    
    Parameters:
    
    value - the value of the segment. If the segmentPrefixLength is non-null, the network prefix of the value is used, and the segment represents all segment values with the same network prefix.
    
    segmentPrefixLength - the segment prefix, which can be null
  - IPv4AddressSegment
```
public IPv4AddressSegment(int lower,
                          int upper,
                          java.lang.Integer segmentPrefixLength)
```
    Constructs a segment of an IPv4 address that represents a range of values.
    
    Parameters:
    
    segmentPrefixLength - the segment prefix length, which can be null. If segmentPrefixLength is non-null, this segment represents a range of segment values with the given network prefix length.
    
    lower - the lower value of the range of values represented by the segment. If segmentPrefixLength is non-null, the lower value becomes the smallest value with the same network prefix.
    
    upper - the upper value of the range of values represented by the segment. If segmentPrefixLength is non-null, the upper value becomes the largest value with the same network prefix.

    Description copied from class: IPAddressSegment
    
    returns a new segment masked by the given mask This method applies the mask first to every address in the range, and it does not preserve any existing prefix. The given prefix will be applied to the range of addresses after the mask. If the combination of the two does not result in a contiguous range of addresses, then IPAddressTypeException is thrown.
