1.0 Abstract

   The Dynamic Host Configuration Protocol (DHCP) [RFC 2131] provides a
   framework for passing configuration information to hosts on a TCP/IP
   network. DHCP includes options for specific configuration parameters
   [RFC 2132].  This document defines options that carry NetWare/IP
   domain name and NetWare/IP sub-options to DHCP clients.

1.1 Requirements

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   document are to be interpreted as described in RFC 2119 [RFC 2119].

1.2 Terminology

   This document uses the following terms:

      o "DHCP client"

        A DHCP client is an Internet host using DHCP to obtain
        configuration parameters such as a network address.

Droms & Fong                Standards Track                     [Page 1]
RFC 2242         NetWare/IP Domain Name and Information    November 1997

      o "DHCP server"

        A DHCP server is an Internet host that returns configuration
        parameters to DHCP clients.

2. The NetWare/IP Domain Name option

   This option code is used to convey the NetWare/IP domain name used by
   the NetWare/IP product. The NetWare/IP Domain in the option is an NVT
   ASCII [RFC 854] string whose length is inferred from the option 'len'

   The code for this option is 62, and its maximum length is 255.

          Code  Len    NetWare/IP Domain Name
        |  62 |  n  |  c1  |  c2  |  c3  |  ...

   The 'len' field gives the length of the NetWare/IP Domain Name.

3. The NetWare/IP Information option

   The NetWare/IP option code will be used to convey all the NetWare/IP
   related information except for the NetWare/IP domain name.

   The code for this option is 63, and its maximum length is 255. A
   number of NetWare/IP sub-options will be conveyed using this option
   code.  The 'len' field for this option gives the length of the option
   data, which includes the sub-option code, length and data fields.

   Each sub-option contains in sequential order, a one byte sub-option
   code, a one byte length, and an optional multiple byte value field.
   The sub-option length gives the length of the value field for the
   sub-option. The example below illustrates the use of the 'len' and
   sub-option length fields in this option.

   One and only one of the following four sub-options must be the first
   sub-option to be present in option 63 encoding. Each of them is
   simply a type length pair with length set to zero.



      The responding DHCP server does not have any NetWare/IP
      information configured.

RFC 2242         NetWare/IP Domain Name and Information    November 1997


      All NetWare/IP information is present in the 'options' area of the
      DHCP response packet.


      All NetWare/IP information is present in the 'sname' and, if
      necessary, 'file' fields of the DHCP response packet. If used, the
      following DHCP server behavior is required: within the 'options'
      area, option 63 is present with its length field set to 2. The
      first byte of the value field is set to NWIP_EXIST_IN_SNAME_FILE
      tag and the second byte is set to zero.  Both option 62 and option
      63 will be placed in the area covered by the sname and file
      fields. Option 62 is encoded normally. Option 63 is encoded with
      its tag, length and value. The value field does not contain any of
      the first four sub-options described herein.


      Neither 'options' area nor 'sname' field can accommodate the
      NetWare/IP information.

   sub-options is set, one or more of the following sub-options may be

   NSQ_BROADCAST (code 5)
