## 28.10 java.net.InetAddress (JDK 1.0)

###

This class represents an Internet address, and is used when creating `DatagramPacket` or `Socket` objects. The class does not have a public constructor function, but instead supports three static methods which return one or more instances of `InetAddress`. `getLocalHost()` returns an `InetAddress` for the local host. `getByName()` returns the `InetAddress` of a host specified by name. `getAllByName()` returns an array of `InetAddress` that represents all of the available addresses for a host specified by name. Instance methods are `getHostName()`, which returns the hostname of an `InetAddress`, and `getAddress()`, which returns the Internet IP address as an array of bytes, with the highest-order byte as the first element of the array.

    public final class InetAddress extends Object implements Serializable {
        // No Constructor
        // Class Methods
                public static InetAddress[] getAllByName(String host) throws UnknownHostException;
                public static InetAddress getByName(String host) throws UnknownHostException;
                public static InetAddress getLocalHost() throws UnknownHostException;
        // Public Instance Methods
                public boolean equals(Object obj);  // Overrides Object
                public byte[] getAddress();
                public String getHostAddress();
                public String getHostName();
                public int hashCode();  // Overrides Object
            1.1public boolean isMulticastAddress();
                public String toString();  // Overrides Object
    }
