RFC 2241                     DHCP Options                  November 1997


   The NDS Tree Name Option and the NDS Context Option carry 16-bit
   Unicode text encoded into an octet stream using UTF-8 [4]. A complete
   DHCP implementation can represent of the entire Unicode character set
   supported by NDS. At the same time, 7-bit ASCII text is unchanged by
   the UTF-8 transformation. In environments where the NDS tree name and
   context are restricted to the range of 7-bit ASCII characters, ASCII-
   only DHCP clients and servers can support these options by using the
   ASCII text as the UTF-8 encoded data.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119. [2]

2. NDS Servers Option

   This option specifies one or more NDS servers for the client to
   contact for access to the NDS database. Servers SHOULD be listed in
   order of preference.

   The code for this option is 85. The minimum length of this option is
   4 octets, and the length MUST be a multiple of 4.

      Code   Len        Address 1               Address 2
     +-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+--
     | 85  |  n  |  a1 |  a2 | a3  |  a4 |  a1 |  a2 |  a3 |  a4 |  ...
     +-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+--


3. NDS Tree Name Option

   This option specifies the name of the NDS tree the client will be
   contacting. NDS tree names are 16-bit Unicode strings. For
   transmission in the NDS Tree Name Option, an NDS tree name is
   transformed into octets using UTF-8. The string should NOT be zero
   terminated.

   The code for this option is 86. The maximum possible length for this
   option is 255 bytes.

       Code Len  NDS Tree Name
      +----+----+----+----+----+----+--
      | 86 | n  | c1 | c2 | c3 | c4 |  ...
      +----+----+----+----+----+----+--
