o equals(Object)
Compares this object against the specified object.
o getAddress()
Returns the raw IP address in network byte order.
o getAllByName(String)
Given a hostname, returns an array of all the corresponding InetAddresses.
o getByName(String)
Returns a network address for the indicated host.
o getHostAddress()
Returns the IP address string "%d.%d.%d.%d"
o getHostName()
Gets the hostname for this address; also the key in the hashtable.
o getLocalHost()
Returns the local host.
o hashCode()
Returns a hashcode for this InetAddress.
o toString()
Converts the InetAddress to a String.

Methods

o getHostName 
  public String getHostName()
Gets the hostname for this address; also the key in the hashtable. If the host is equal to null, then this address refers to any of the local machine's available network addresses.
o getAddress 
  public byte[] getAddress()
Returns the raw IP address in network byte order. The highest order byte position is in addr[0]. To be prepared for 64-bit IP addresses n array of bytes is returned.
Returns:
raw IP address in network byte order.
o getHostAddress 
  public String getHostAddress()
Returns the IP address string "%d.%d.%d.%d"
Returns:
raw IP address in a string format
o hashCode 
  public int hashCode()
Returns a hashcode for this InetAddress.
Overrides:
hashCode in class Object
o equals 
  public boolean equals(Object obj)
Compares this object against the specified object.
Parameters:
obj - the object to compare against.
Returns:
true if the objects are the same; false otherwise.
Overrides:
equals in class Object
o toString 
  public String toString()
Converts the InetAddress to a String.
Overrides:
toString in class Object
o getByName 
  public static synchronized InetAddress getByName(String host) throws UnknownHostException
Returns a network address for the indicated host. A host name of null refers to default address for the local machine. A local cache is used to speed access to addresses. If all addresses for a host are needed, use the getAllByName() method.
Parameters:
host - the specified host
Throws: UnknownHostException
If the address is unknown.
o getAllByName 
  public static synchronized InetAddress[] getAllByName(String host) throws UnknownHostException
Given a hostname, returns an array of all the corresponding InetAddresses.
Throws: UnknownHostException
If the host name could not be resolved
o getLocalHost 
  public static InetAddress getLocalHost() throws UnknownHostException
Returns the local host.
Throws: UnknownHostException
If the host name could not be resolved
