    @class Win360::Win360IpAddress

    NOTE: Socket network communication on the Xbox360 is only provided
    for debugging and development purposes. For actual multiplayer and
    Xbox Live related stuff, use the Xbox-specific add-on modules!
    (which don't exist yet, ha).

    Represents an IP address, consisting of a IPv4 host address
    and a port number. Performs automatic name lookup on the host name.
    Can extract address information from an URI and    
    automatically converts host names to addresses, and offers the special 
    hostnames "localhost", "any", "broadcast", "self" and "inetself" where:

    - "localhost" will translate to 127.0.0.1
    - "any" will translate to INADDR_ANY, which is 0.0.0.0
    - "broadcast" will translate to INADDR_BROADCAST, which is 255.255.255.255
    - "self" will translate to the first valid tcp/ip address for this host
      (there may be more then one address bound to the host)
    - "inetself" will translate to the first host address which is not 
      a LAN address (which is not a class A, B, or C network) if none such
      exists the address will fall back to "self"
