Status of this Memo

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.
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 [RFC 2119].
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.

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’ field.
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 t...
