Method Detail

getByAddress

public static IPAddress getByAddress(byte[] addr)
                              throws UnknownHostException

Returns an InetAddress object given the raw IP address. The argument is in network byte order: the highest order byte of the address is in getAddress()[0]. This method doesn't block, i.e. no reverse name service lookup is performed.
IPv4 address byte array must be 4 bytes long and IPv6 byte array must be 16 bytes long

Parameters:

addr - - the raw IP address in network byte order

Returns:

an InetAddress object created from the raw IP address.

Throws:

UnknownHostException

getByAddress

public static IPAddress getByAddress(int addr)
                              throws UnknownHostException

Throws:

UnknownHostException

parseHostAddress

public static IPAddress parseHostAddress(String hostAddress)
                                  throws UnknownHostException

Parse a literal representation of an IP address and returns the corresponding IPAddress class.

Parameters:

hostAddress -

Returns:

Throws:

UnknownHostException

getAddress

public byte[] getAddress()

Returns the raw IP address of this InetAddress object. The result is in network byte order: the highest order byte of the address is in getAddress()[0].

Returns:

the raw IP address of this object.

getHostAddress

public String getHostAddress()

Returns the IP address string in textual presentation.

Returns:

the raw IP address in a string format.

isAnyLocalAddress

public boolean isAnyLocalAddress()

Utility routine to check if the InetAddress in a wildcard address.

Returns:

a boolean indicating if the Inetaddress is a wildcard address.

isLinkLocalAddress

public boolean isLinkLocalAddress()

Utility routine to check if the InetAddress is an link local address.

Returns:

a boolean indicating if the InetAddress is a link local address; or false if address is not a link local unicast address.

isLoopbackAddress

public boolean isLoopbackAddress()

Utility routine to check if the InetAddress is a loopback address.

Returns:

a boolean indicating if the InetAddress is a loopback address; or false otherwise.

isMCGlobal

public boolean isMCGlobal()

Utility routine to check if the multicast address has global scope.

Returns:

a boolean indicating if the address has is a multicast address of global scope, false if it is not of global scope or it is not a multicast address

isMCLinkLocal

public boolean isMCLinkLocal()

Utility routine to check if the multicast address has link scope.

Returns:

a boolean indicating if the address has is a multicast address of link-local scope, false if it is not of link-local scope or it is not a multicast address

isMCNodeLocal

public boolean isMCNodeLocal()

Utility routine to check if the multicast address has node scope.

Returns:

a boolean indicating if the address has is a multicast address of node-local scope, false if it is not of node-local scope or it is not a multicast address

isMCOrgLocal

public boolean isMCOrgLocal()

Utility routine to check if the multicast address has organization scope.

Returns:

a boolean indicating if the address has is a multicast address of organization-local scope, false if it is not of organization-local scope or it is not a multicast address

isMCSiteLocal

public boolean isMCSiteLocal()

Utility routine to check if the multicast address has site scope.

Returns:

a boolean indicating if the address has is a multicast address of site-local scope, false if it is not of site-local scope or it is not a multicast address

isMulticastAddress

public boolean isMulticastAddress()

Utility routine to check if the InetAddress is an IP multicast address.

Returns:

isSiteLocalAddress

public boolean isSiteLocalAddress()

Utility routine to check if the InetAddress is a site local address.}

Returns:

a boolean indicating if the InetAddress is a site local address; or false if address is not a site local unicast address.
