   - The SLIST data structure discussed in [RFC-1034].

     This structure keeps track of the state of a request if it
     must wait for answers from foreign name servers.

7.2. Sending the queries

As described in [RFC-1034], the basic task of the resolver is to
formulate a query which will answer the client's request and direct that
query to name servers which can provide the information.  The resolver
will usually only have very strong hints about which servers to ask, in
the form of NS RRs, and may have to revise the query, in response to
CNAMEs, or revise the set of name servers the resolver is asking, in
response to delegation responses which point the resolver to name
servers closer to the desired information.  In addition to the
information requested by the client, the resolver may have to call upon
its own services to determine the address of name servers it wishes to
contact.
