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 resolver 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.
New DNS MIB objects have been defined to be used in conjunction
with the Internet MIB to allow access and control of the DNS via
SNMP by the Internet community.
2 The DNS Model
In theory, the DNS world is pretty simple. There are two kinds
of entities: resolvers and name servers. Resolvers ask ques-
tions. Name servers answer them. The real world, however, is not
so simple. Implementors have made widely differing choices about
how to divide DNS functions between resolvers and servers. They
have also constructed various sorts of exotic hybrids. The most
difficult task in defining this MIB was to accommodate this wide
range of entities without having to come up with a separate MIB
for each.
Document Expiration Date - May 17, 1993 - Austein, Saperia 1
We divided up the various DNS functions into two, non-
overlapping classes, called 'resolver functions' and 'name
server functions'. A DNS entity that performs what we define
as resolver functions contains a resolver, and therefore must
implement the MIB groups required of all resolvers. Some re-
solvers also implement 'optional' functions such as a cache. In
this example, they will also implement the cache group contained
in this MIB. A DNS entity which implements name server functions
is considered to be a name server, and must implement the MIB
groups required for name servers. If the same piece of software
performs both resolver and server functions, we imagine that it
contains both a resolver and a server.
In our model, a resolver is a program (or piece thereof) which
obtains resource records from servers. Normally it does so at
the behest of an application, but may also do so as part of its
own operation. A resolver sends DNS protocol queries and re-
ceives DNS protocol replies. A resolver neither receives queries
nor sends replies. A full service resolver is one that knows
how to resolve queries: it obtains the needed resource records
by contacting a server authoritative for the records desired.
A stub resolver does not know how to resolve queries: it sends
all queries to a local name server, setting the recursion de-
sired flag to indicate that it hopes that the name server will
be willing resolve the query. A resolver may (optionally) have
a cache for remembering previously acquired resource records.
It may also have a negative cache for remembering names or data
that have been determined not to exist.
A name server is a program (or piece thereof) that provides
resource records to resolvers. All references in this document
to 'a name server' imply 'the name server's role'. (In some
cases the name server's role and the resolver's role might
be combined into a single program.) A name server receives
DNS protocol queries and sends DNS protocol replies. A name
server neither sends queries nor receives replies. As a con-
sequence, name servers do not have caches. Normally, a name
server would expect to receive only those queries for which it
2 Document Expiration Date - May 17, 1993 - Austein, Saperia
could respond to with authoritative information. However, if
a name server receives a query that it cannot respond to with
purely authoritative information, it may choose to try to obtain
the necessary additional information from a resolver which may
or may not be a separate process.
3 Selected Objects
Many of the objects included in this memo have been created from
information contained in the DNS specification. The DNS spec-
ification is found in Domain Names - Concepts and Facilities
(RFC 1034) and Domain Names - Implementation and Specification
(RFC 1035), as amended and clarified by Requirements for In-
ternet Hosts - Application and Support (RFC1123). Additional
usage information is found in the Domain Administrators Guide
(RFC 1032), and the Domain Administrators Operations Guide (RFC
1033). Other objects have been created based on experience with
existing DNS management tools, expected operational need, and
the statistics generated by existing DNS implementations. These
objects have been ordered into groups as follows:
o General Configuration Group
o Resolver Configuration Group
o Server Configuration Group
o Resolver Counter Group
o Server Counter Group
o Records Group
o Resolver Cache Group
o Resolver Negative Cache Group
o Resolver Statistics Group
Document Expiration Date - May 17, 1993 - Austein, Saperia 3
o Server Management Group
The ordering of objects into these groups reflects the DNS model
in which the resolver and server functions can be separate
pieces of code which may or may not reside on the same host.
This approach accommodates common implementations such as BIND,
but it is not constrained by that or any other implementation
paradigm.
Some 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.
4 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
Names - Implementation and Specification RFC 1035.

4.1 Format of Definitions
An object in this memo is specified by five fields of informa-
tion: Object, Syntax, Description, 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.
DESCRIPTION: 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.
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.
4.2 Textual Conventions
Several datatypes have been introduced as a textual conven-
tions in this DNS MIB document. These additions will facilitate
the common understanding of information used by the DNS. No
changes to the SMI or the SNMP are necessary to support these
conventions which are described in 5.0 (Object Definitions).

DnsName ::= OCTET STRING
-- A DNS name is a sequence of labels. When DNS names are displayed,
-- the boundaries between labels are typically indicated by dots (e.g.
-- "Acme" and "COM" are labels in the name "Acme.COM" ). In the DNS
-- protocol, however, no such separators are needed because each label
-- is encoded as a length octet followed by the indicated number of
-- octets of label. For example, "Acme.COM" is encoded as the octet
-- sequence { 4, 'A', 'c', 'm', 'e', 3, 'C', 'O', 'M', 0 } (the final
-- 0 is the length of the name of the root domain, which appears
-- implicitly at the end of any DNS name). This MIB uses the same
-- encoding as the DNS protocol.
-- A DnsName must always be a fully qualified name. It is an error to
-- encode a relative domain name as a DnsName without first making it a
-- fully qualified name.
DnsClass ::= INTEGER (0..65535)
-- This data type is used to represent the class values which appear
-- in Resource Records in the DNS. A 16-bit unsigned integer is
-- used to allow room for new classes of records to be defined.
-- Existing standard classes are listed in the DNS specification.
DnsType ::= INTEGER (0..65535)
-- This data type is used to represent the type values which appear
-- in Resource Records in the DNS. A 16-bit unsigned integer is

-- Existing standard QTypes are listed in DNS specification.
DnsTime ::= INTEGER
-- DnsTime values are 32-bit unsigned integers which measure time in
-- seconds.
DnsValid ::= INTEGER { valid (1), clear (2) }
-- Many of the tables in this MIB have as one of their columns, an
-- object which can be set to a value of 2 to delete that
-- row of the table. If a read operation is performed on this
-- object, a value of 1 is returned to indicate a valid row in the

-- Server Counter Group
-- The implementation of the Server Counter Group is mandatory for
-- all systems which offer either recursive or non recursive server
-- software functions.
-- Several of the objects in this group make distinctions between
-- queries which originate with the local host, within the same
-- zone as the local host or come from outside the zone of the
-- server. The purpose of these distinctions is to allow for
-- implementations to group queries and responses on this basis.
-- One way in which servers may make these distinctions is by
-- looking at the source IP address of the DNS query. If the
-- source of the query is 'your own' then the query should be
-- counted as 'yourself' - local host. If the source of the query
-- matches an 'access list' - the the query came from a friend,
-- that is; within the local zone. What constitutes an 'access
-- list' is implementation dependent and could be as simple as all
-- hosts on the same IP network as the DNS server are classed as in
-- the local zone and are 'friends'. In order to avoid double
-- counting, the following rules apply:
-- 1. No host is in more than one of the three groups defined above.
-- 2. All queries from the local host are always counted in the
-- 'yourself' group regardless of what the access list, if any,
-- says.
-- 3. The access list should not define 'your friends' in such a way
-- that it includes all hosts, that is 'not everybody is your
-- friend'.
