      /**

       * Fineza interpretar o seguinte paragrafo (vindo do RFC 2131...):

       * 

       *    [1] If the 'giaddr' field in a DHCP message from a client is non-zero,

       *    the server sends any return messages to the 'DHCP server' port on the

       *    BOOTP relay agent whose address appears in 'giaddr'. [2] If the 'giaddr '

       *    field is zero and the 'ciaddr' field is nonzero, then the server

       *    unicasts DHCPOFFER and DHCPACK messages to the address in 'ciaddr'.

       *    [3] If 'giaddr' is zero and 'ciaddr' is zero, and the broadcast bit is

       *    set, then the server broadcasts DHCPOFFER and DHCPACK messages to

       *    0xffffffff. [4] If the broadcast bit is not set and 'giaddr' is zero and

       *    'ciaddr' is zero, then the server unicasts DHCPOFFER and DHCPACK

       *    messages to the client's hardware address and 'yiaddr' address.  In

       *    all cases, when 'giaddr' is zero, the server broadcasts any DHCPNAK

       *    messages to 0xffffffff.

Aaargh! Eu vou me dar férias, eu prometo!
