Applications should use the methods getLocalHost (I-§4.4.6), getByName (I-§4.4.4), or getAllByName (I-§4.4.3) to create a new InetAddress instance.

The result is true if and only if the argument is not null and it represents the same IP address as this object.

Two instances of InetAddress represent the same IP address if the length of the byte arrays returned by getAddress (I-§4.4.2) is the same for both, and each of the array components is the same for the byte arrays.

Parameters:

obj - the object to compare against

Returns:

true if the objects are the same; false otherwise.

Overrides:

equals in class Object (I-§1.12.3).

Determines the raw IP address of this InetAddress object. The result is in network byte order: the highest order byte of the address is in get-Address()[0].

Returns:

the raw IP address of this object.

Parameters:

host - the name of the host

Returns:

an array of all the IP addresses for a given host name.

Throws

UnknownHostException (I-§4.18)

If no IP address for the host could be found.

Determines the IP address of a host, given the host's name. The host name can either be a machine name, such as "java.sun.com" or a string representing its IP address, such as "206.26.48.100".

Parameters:

host - the specified host, or null for the local host

Returns:

an IP address for the given host name.

Throws

UnknownHostException (I-§4.18)

If no IP address for the host could be found.

Returns:

the host name for this IP address.

Returns:

the IP address of the local host.

Throws

UnknownHostException (I-§4.18)

If no IP address for the host could be found.

Returns:

a hash code value for this IP address.

Overrides:

hashCode in class Object (I-§1.12.6).

Returns:

a string representation of this IP address.

Overrides:

toString in class Object (I-§1.12.9).
