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." REFERENCE "RFC-1034 section 3.1." SYNTAX OCTET STRING (SIZE (0..255)) 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." REFERENCE "RFC-1034 section 3.1, RFC-1448 section 4.1."

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.
