    The Dynamic Host Configuration Protocol (DHCP) [1] provides a
    framework for passing configuration information to hosts on a TCP/IP
    network.  Configuration parameters and other control information are
    carried in tagged data items that are stored in the 'options' field
    of the DHCP message.  The data items themselves are also called
    "options."
 
    Each option is assigned a one-octet option code.  Options 128-254 are
    reserved for local use and at this time over half of the available
    options in the range 0-127 and option 255 have been assigned.  This

 Definition of option 127
 
    Option code 127 indicates that the DHCP option has a two-octet
    extended option code.  The format of these options is:

    encoded and carried in DHCP messages identically to the options
    defined in RFC 1533 [2].  The high-order and low-order octets of the
    extended option code are stored in 'oh' and 'ol', respectively.  The
    number of octets given in the 'len' field includes the two-octet
    extended option code.
 
    The two-octet extended option codes will be assigned through the
    mechanisms defined for the assignment of new options [3] after the
    current one-octet option codes have been exhausted.
 
+Definition of option 126
+
+   This option is used by a DHCP client to request values for specified
+   configuration paramaters that are identified by extended option codes
+   as defined above.  The list of n requested parameters is specified as
+   2n octets, where each pair of octets is a valid extended option code.
+
+   The client MAY list the options in order of preference.  The DHCP
+   server is not required to return the options in the requested order,
+   but MUST try to insert the requested options in the order requested
+   by the client.
+
+   The code for this option is 126.  Its minimum length is 2.
