From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Called before the object's memory is reclaimed by the VM.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public boolean isAnyLocalAddress ()

Since: API Level 1

Returns whether the represented address is the local wildcard ANY address or not.

Returns

true if this instance represents the wildcard ANY address, false otherwise.

public boolean isLinkLocalAddress ()

Since: API Level 1

Returns whether this address has a link-local scope or not.

RFC 3484
Default Address Selection for Internet Protocol Version 6 (IPv6) states IPv4 auto-configuration addresses, prefix 169.254/16, IPv4 loopback addresses, prefix 127/8, are assigned link-local scope.

Returns

true if this instance represents a link-local address, false otherwise.

public boolean isLoopbackAddress ()

Since: API Level 1

Returns whether the represented address is a loopback address or not. Loopback IPv4 addresses are prefixed with: 011111111 = 127.

Returns

true if this instance represents a lookback address, false otherwise.

public boolean isMCGlobal ()

Since: API Level 1

Returns whether the address is a global multicast address or not. Valid MCGlobal IPv4 addresses are 224.0.1.0 - 238.255.255.255.

Returns

true if the address is in the global multicast group, false otherwise.

public boolean isMCLinkLocal ()

Since: API Level 1

Returns whether the address is a link-local multicast address or not. The valid range for IPv4 link-local addresses is: 224.0.0.0 to 239.0.0.255 Hence a mask of 111000000000000000000000 = 0xE00000.

Returns

true if this instance represents a link-local address, false otherwise.

public boolean isMCNodeLocal ()

Since: API Level 1

Returns whether the address has a node-local scope or not. This method returns always false because there are no valid IPv4 node-local addresses.

Returns

false for all IPv4 addresses.

public boolean isMCOrgLocal ()

Since: API Level 1

Returns whether the address is a organization-local multicast address or not. The valid range for IPv4 organization-local addresses is: 239.192.0.0 to 239.195.255.255 Hence masks of 11101111 11000000 to 11101111 11000011 are valid. 0xEFC0 to 0xEFC3

Returns

true if this instance represents a organization-local address, false otherwise.

public boolean isMCSiteLocal ()

Since: API Level 1

Returns whether the address is a site-local multicast address or not. The valid range for IPv4 site-local addresses is: 239.255.0.0 to 239.255.255.255 Hence a mask of 11101111 11111111 = 0xEFFF.

Returns

true if this instance represents a site-local address, false otherwise.

public boolean isMulticastAddress ()

Since: API Level 1

Returns whether the represented address is a multicast address or not. Valid IPv4 multicast addresses are prefixed with 1110 = 0xE.

Returns

true if this instance represents a multicast address, false otherwise.

public boolean isSiteLocalAddress ()

Since: API Level 1

Returns whether this address has a site-local scope or not.

RFC 3484
Default Address Selection for Internet Protocol Version 6 (IPv6) states IPv4 private addresses, prefixes 10/8, 172.16/12, and 192.168/16, are assigned site-local scope.

Returns

true if this instance represents a site-local address, false otherwise.
