Class IPv6Network

java.lang.Object

com.googlecode.ipv6.IPv6AddressRange

com.googlecode.ipv6.IPv6Network

All Implemented Interfaces:

Comparable<IPv6AddressRange>, Iterable<IPv6Address>

public final class IPv6Network
extends IPv6AddressRange

Immutable representation of an IPv6 network based on an address and a prefix length. An IPv6 network is also an IPv6 address range (but not all ranges are valid networks).

Method Detail

fromAddressAndMask

public static IPv6Network fromAddressAndMask(IPv6Address address,
                             IPv6NetworkMask networkMask)

Create an IPv6 network from an IPv6Address and an IPv6NetworkMask

Parameters:

address - IPv6 address (the network address or any other address within the network)

networkMask - IPv6 network mask

Returns:

IPv6 network

fromTwoAddresses

public static IPv6Network fromTwoAddresses(IPv6Address one,
                           IPv6Address two)

Create an IPv6 network from the two addresses within the network. This will construct the smallest possible network ("longest prefix length") which contains both addresses.

Parameters:

one - address one

two - address two, should be bigger than address one

fromString

public static IPv6Network fromString(String string)

Create an IPv6 network from its String representation. For example "1234:5678:abcd:0:0:0:0:0/64" or "2001::ff/128".

Parameters:

string - string representation

Returns:

IPv6 network

split

public Iterator<IPv6Network> split(IPv6NetworkMask size)

Split a network in smaller subnets of a given size.

Parameters:

size - size (expressed as IPv6NetworkMask) of the subnets

Returns:

iterator of the splitted subnets.

Throws:

IllegalArgumentException - if the requested size is bigger than the original size

toString

public String toString()

Overrides:

toString in class IPv6AddressRange

toLongString

public String toLongString()

Overrides:

toLongString in class IPv6AddressRange

Returns:

like toString but without using shorthand notations for addresses

equals

public boolean equals(Object o)

Overrides:

equals in class IPv6AddressRange

hashCode

public int hashCode()

Overrides:

hashCode in class IPv6AddressRange

getNetmask

public IPv6NetworkMask getNetmask()
