Method Detail

localNetworkAddresses

@Deprecated
public static List<InetAddress> localNetworkAddresses()
                                               throws UnknownHostException,
                                                      SocketException

Deprecated.

Throws:

UnknownHostException

SocketException

localhostNetworkAddresses

public static List<InetAddress> localhostNetworkAddresses()
                                                   throws UnknownHostException,
                                                          SocketException

Return list of InetAddress for localhost that are not loopback addresses (e.g., 127.0.0.1)

Returns:

address list with size() >= 1

Throws:

UnknownHostException

SocketException

scanRange

public static Collection<InetAddress> scanRange(InetAddress addr,
                                int count,
                                int msTimeout)

Scan a range of InetAddresses starting with the given address

Parameters:

start - starting address of search; null implies subnetAddress0(null,24)

count - number of addresses in range

msTimeout - maximum time to wait for each host

subnetAddress0

public static InetAddress subnetAddress0(InetAddress addr,
                         int subnetBits)

Return first address on subnet containing given address

Parameters:

addr - any machine in subnet

subnetBits - the number of bits in subnet mask. Many small networks use 24.

Returns:

first address on subnet. E.g., subnetAddress(10.0.1.88, 25) -> 10.0.1.0

asLongAddress

public static long asLongAddress(InetAddress addr)

getAddresses

public List<InetAddress> getAddresses()

asInetAddress

public static InetAddress asInetAddress(long addr)
                                 throws UnknownHostException

Throws:

UnknownHostException
