  This draft document will be submitted to the RFC editor as
  a proposed extension to the SNMP MIB. Distribution of this
  document is unlimited. Please send comments or corrections to

  Abstract
  
  This memo defines a set of DNS (Domain Name System) exten-
  sions that have been created for the Internet MIB. When used
  in conjunction with the Structure of Management Information (RFC
  1155), the Management Information Base for Network Management
  of TCP/IP-based internets (RFC 1213) and the Simple Network
  Management Protocol (RFC 1157), it will be possible to provide
  integrated network management of DNS client and server soft-
  ware in standard TCP/IP based environments. This document was
  produced by the DNS working group.

  1  Introduction
  
  With the adoption of The Simple Network Management Protocol (RFC
  1157), the Management Information Base for network management of
  TCP/IP-based internets (RFC 1213), and the Structure of Manage-
  ment Information (RFC 1155) by the Internet, and a large number
  of vendor implementations of these standards in commercially
  available products, it became possible to provide a higher level
  of effective network management in TCP/IP-based internets than
  previously available. With the growth in the use of these stan-
  dards, it has become possible to consider the management of
  other elements of the infrastructure beyond the basic TCP/IP
  protocols. A key element of the TCP/IP infrastructure is the
  DNS.
  
  Up to this point there has been no mechanism to integrate the
  management of the DNS with SNMP-based managers. This memo pro-
  vides the mechanisms by which IP-based management stations can
  effectively manage DNS client and Server software in an inte-
  grated fashion through the use of the standard Internet SMI, MIB
  and Simple Network Management Protocol.
  
  DNS objects have been defined to be used in conjunction with the
  Internet MIB to allow access and control of these new objects by
  the Internet community.
  
  
  2  Selected Objects
  
  The objects included in this memo have been created from infor-
  mation contained in the relevant DNS related RFCs which include:
  Domain Administrators Guide (RFC 1032), Domain Administrators
  Operations Guide (RFC 1033) Domain Names - Concepts and Facili-
  ties (RFC 1034), Domain Names - Implementation and Specification
  (RFC 1035), and Requirements for Internet Hosts - Application
  and Support (RFC 1123). In addition, objects have been created

   Internet Draft - DNS MIB - March 5 1992
  
  
  
  based on expected operational need and from the example of ex-
  isting DNS specific tools. These objects have be ordered into
  groups as follows:
  
  
  o  General Configuration Group
  
  o  Client Configuration Group
  
  o  Server Configuration Group
  
  o  Resolver Counter Group
  
  o  Server Counter Group
  
  o  Full Service Resolver Counter Group
  
  o  Recursive Server Counter Group
  
  o  Non Recursive Server Counter Group
  
  o  A Records Group
  
  o  NS Records Group
  
  o  CNAME Records Group
  
  o  WKS Records Group
  
  o  PTR Records Group
  
  o  HINFO Records Group
  
  o  MX Records Group
  
  o  Undefined Records Group
  
  o  Server Management Group
  
  Many of the objects defined in this memo have been created from
  information contained in existing configuration files used by
  many DNS implementations. This information has been converted
  into a standard form using the Internet Standard SMI defined in
  RFC 1155.

  3  Objects
  
  The objects in this memo are described using the standard Inter-
  net SMI and BER of RFC 1155. Each object description includes
  the objects name, its syntax and encoding. Just as with objects
  supported in the MIB (RFC 1156), an object name is identified
  with an object identifier which has been administratively as-
  signed. This identifies an Object Type. When an object type
  is combined with a specific instance - the particular object
  is uniquely identified. Use of Object Descriptors in this memo
  is consistent with that of RFC 1156 - meaning that they are
  text strings meant to be read by humans. The descriptors have
  been created from a variety of sources. For the most part, the
  descriptions are influenced by by the DNS related RFCs noted
  above. For example, the descriptors for counters used for the
  various types of queries of DNS records are influenced by the
  definitions used for the various record types found in Domain
  Concepts and Facilities - RFC 1034.
  
  3.1  Format of Definitions
  
  An object in this memo is specified by five fields of informa-
  tion: Object, Syntax, Definition, Access, and Status.
  
  The OBJECT is a textual name (OBJECT DESCRIPTOR) for that ob-
  ject type combined with an administratively obtained OBJECT
  IDENTIFIER.
  
  SYNTAX : For each object type, its abstract syntax is presented
  using the ASN.1 specified in RFC 1155.
  
  DEFINITION: A general description of the object type.
  
  ACCESS : The standard access keywords supported in RFC 1156 are
  used. The keywords used in this MIB are: read-only, read-write,
  and, not-accessible.

   Internet Draft - DNS MIB - March 5 1992
  
  
  
  STATUS : The status field is used to describe with a single
  keyword whether the object type is mandatory or optional. Status
  keywords of obsolete and deprecated are not used in this memo
  since this is the first version of the DNS MIB.
  
  
  
  3.2  Textual Conventions
  
  A new datatype has been introduced as a textual convention in
  this DNS MIB document. This addition will facilitate the common
  understanding of information used by the DNS. No changes to
  the SMI the the SNMP are necessary to support these conventions
  which are described in 4.0 (Object Definitions).

       -- One way in which servers may make these distinctions is by
       -- looking at the source IP address of the DNS query.  If the
