    STATUS  current

    DESCRIPTION

            "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."

DnsNameAsIndex ::= TEXTUAL-CONVENTION

    STATUS  current

    DESCRIPTION

            "This textual convention is like a DnsName, but is used

            as an index componant in tables.  Alphabetic characters

            in names of this type are restricted to uppercase: the

            characters 'a' through 'z' are mapped to the characters

            'A' through 'Z'.  This restriction is intended to make

            the lexical ordering imposed by SNMP useful when applied

            to DNS names.

            Note that it is theoretically possible for a valid DNS

            name to exceed the allowed length of an SNMP object

            identifer, and thus be impossible to represent in tables

            in this MIB that are indexed by DNS name.  Sampling of

            DNS names in current use on the Internet suggests that

            this limit does not pose a serious problem in practice."

-- Server Optional Counter Group

-- The Server Optional Counter Group is intended for those systems

-- which make distinctions between the different sources of the DNS

-- queries as defined below.

--

-- Objects in this group are implemented on servers which distinguish

-- between queries which originate from the same host as the server,

-- queries from one of an arbitrary group of hosts that are on an

-- access list defined by the server, and queries from hosts that do

-- not fit either of these descriptions.

--

-- The objects found in the Server Counter group are totals.  Thus if

-- one wanted to identify, for example, the number of queries from

-- `remote' hosts which have been given authoritative answers, one

-- would subtract the current values of ServOptCounterFriendsAuthAns

-- and ServOptCounterSelfAuthAns from servCounterAuthAns.

--

-- 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 query

-- came from a friend.  What constitutes an `access list' is

-- implementation dependent and could be as simple as a rule that all

-- hosts on the same IP network as the DNS server are classed

-- `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.'
