-- 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.'
