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.

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.

Public Methods

public boolean isAnyLocalAddress ()

Added in API level 1

Returns whether this is the IPv6 unspecified wildcard address :: or the IPv4 "any" address, 0.0.0.0 .

public boolean isLinkLocalAddress ()

Added in API level 1

Returns whether this address is a link-local address or not.

Valid IPv6 link-local addresses have the prefix fe80::/10 .

RFC 3484 "Default Address Selection for Internet Protocol Version 6 (IPv6)" states that both IPv4 auto-configuration addresses (prefix 169.254/16 ) and IPv4 loopback addresses (prefix 127/8 ) have link-local scope, but Inet4Address only considers the auto-configuration addresses to have link-local scope. That is: the IPv4 loopback address returns false.

public boolean isLoopbackAddress ()

Added in API level 1

Returns whether this address is a loopback address or not.

Valid IPv4 loopback addresses have the prefix 127/8 .

The only valid IPv6 loopback address is ::1 .

public boolean isMCGlobal ()

Added in API level 1

Returns whether this address is a global multicast address or not.

Valid IPv6 global multicast addresses have the prefix ffxe::/16 , where x is a set of flags and the additional 112 bits make up the global multicast address space.

Valid IPv4 global multicast addresses are the range of addresses from 224.0.1.0 to 238.255.255.255 .

public boolean isMCLinkLocal ()

Added in API level 1

Returns whether this address is a link-local multicast address or not.

Valid IPv6 link-local multicast addresses have the prefix ffx2::/16 , where x is a set of flags and the additional 112 bits make up the link-local multicast address space.

Valid IPv4 link-local multicast addresses have the prefix 224.0.0/24 .

public boolean isMCNodeLocal ()

Added in API level 1

Returns whether this address is a node-local multicast address or not.

Valid IPv6 node-local multicast addresses have the prefix ffx1::/16 , where x is a set of flags and the additional 112 bits make up the link-local multicast address space.

There are no valid IPv4 node-local multicast addresses.

public boolean isMCOrgLocal ()

Added in API level 1

Returns whether this address is a organization-local multicast address or not.

Valid IPv6 organization-local multicast addresses have the prefix ffx8::/16 , where x is a set of flags and the additional 112 bits make up the link-local multicast address space.

Valid IPv4 organization-local multicast addresses have the prefix 239.192/14 .

public boolean isMCSiteLocal ()

Added in API level 1

Returns whether this address is a site-local multicast address or not.

Valid IPv6 site-local multicast addresses have the prefix ffx5::/16 , where x is a set of flags and the additional 112 bits make up the link-local multicast address space.

Valid IPv4 site-local multicast addresses have the prefix 239.255/16 .

public boolean isMulticastAddress ()

Added in API level 1

Returns whether this address is a multicast address or not.

Valid IPv6 multicast addresses have the prefix ff::/8 .

Valid IPv4 multicast addresses have the prefix 224/4 .

public boolean isSiteLocalAddress ()

Added in API level 1

Returns whether this address is a site-local address or not.

For the purposes of this method, valid IPv6 site-local addresses have the deprecated prefix fec0::/10 from RFC 1884 , not the modern prefix fc00::/7 from RFC 4193 .

RFC 3484 "Default Address Selection for Internet Protocol Version 6 (IPv6)" states that IPv4 private addresses have the prefix 10/8 , 172.16/12 , or 192.168/16 .

Returns

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