Parameters:

port - port to be added to get socket address.

Returns:

array of broadcast addresses with given port.

getBroadcastAddresses

public static Set<InetAddress> getBroadcastAddresses()

Get a set of broadcast addresses.

Returns:

set of broadcast addresses.

getLoopbackNIF

public static NetworkInterface getLoopbackNIF()

Get a loopback NIF.

Returns:

a loopback NIF, null if not found.

encodeAsIPv6Address

public static final void encodeAsIPv6Address(ByteBuffer buffer,
                                             InetAddress address)
                                      throws RuntimeException

Encode address as IPv6 address.

Parameters:

buffer - byte-buffer where to put encoded data.

address - address to encode.

Throws:

RuntimeException - thrown if address is unsupported.

intToIPv4Address

public static InetAddress intToIPv4Address(int addr)

Convert an integer into an IPv4 INET address.

Parameters:

addr - integer representation of a given address.

Returns:

IPv4 INET address.

ipv4AddressToInt

public static int ipv4AddressToInt(InetAddress addr)

Convert an IPv4 INET address to an integer.

Parameters:

addr - IPv4 INET address.

Returns:

integer representation of a given address.

Throws:

IllegalArgumentException - if the address is really an IPv6 address

getSocketAddressList
