zone, and A further for that cache: 1. Set or obvious the value of recursion offered during the reaction dependant upon whether the name server is ready to offer recursive assistance. If recursive company is obtainable and asked for by using the RD little bit while in the query, drop by stage five, or else step two. two. look for the offered zones with the zone that's the closest ancestor to QNAME. If this kind of zone is identified, head to action three, if not stage 4. three. start off matching down, label by label, in the zone. The matching course of action can terminate numerous techniques: a. If The complete of QNAME is matched, we have discovered the node. If the info within the node is really a CNAME, and QTYPE will not match CNAME, copy the CNAME RR into the answer section with the response, modify QNAME towards the canonical name within the CNAME RR, and return to step one.
b. If your response consists of a much better delegation to other servers, cache the delegation information and facts, and go to action 2. c. In the event the reaction displays a CNAME and that isn't the answer itself, cache the CNAME, change the SNAME to your canonical name inside the CNAME RR and visit step 1. d. If your response demonstrates a servers failure or other weird contents, delete the server in the SLIST and return to phase 3. Step one lookups the cache for the specified information. If the information is during the
