Utility methods for InetAddress implementations.

Summary

Public methods
`static boolean`	`isNumericAddress(String address)` Checks to see if the `address` is a numeric address (such as `"192.0.2.1"` or `"2001:db8::1:2"`).
`static InetAddress`	`parseNumericAddress(String address)` Returns an InetAddress corresponding to the given numeric address (such as `"192.168.0.1"` or `"2001:4860:800d::68"`).

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

isNumericAddress

Added in API level 29

public static boolean isNumericAddress (String address)

Checks to see if the address is a numeric address (such as "192.0.2.1" or "2001:db8::1:2").

A numeric address is either an IPv4 address containing exactly 4 decimal numbers or an IPv6 numeric address. IPv4 addresses that consist of either hexadecimal or octal digits or do not have exactly 4 numbers are not treated as numeric.

This method will never do a DNS lookup.

Parameters
`address`	`String`: the address to parse. This value cannot be `null`.

Returns
`boolean`	true if the supplied address is numeric, false otherwise.

parseNumericAddress

Added in API level 29

public static InetAddress parseNumericAddress (String address)

Returns an InetAddress corresponding to the given numeric address (such as "192.168.0.1" or "2001:4860:800d::68").

See isNumericAddress(java.lang.String) (String)} for a definition as to what constitutes a numeric address.

This method will never do a DNS lookup.

Parameters
`address`	`String`: the address to parse, must be numeric. This value cannot be `null`.

Returns
`InetAddress`	an `InetAddress` instance corresponding to the address. This value cannot be `null`.

Throws
`IllegalArgumentException`	if `address` is not a numeric address.
