What do the DNS servers do with the information learned from the iterative queries?
An iterative name query is one in which a DNS client allows the DNS server to return the best answer it can give based on its cache or zone data. If the queried DNS server does not have an exact match for the queried name, the best possible information it can return is a referral (that is, a pointer to a DNS server authoritative for a lower level of the domain namespace). The DNS client can then query the DNS server for which it obtained a referral. It continues this process until it locates a DNS server that is authoritative for the queried name, or until an error or time-out condition is met.This process is sometimes referred to as "walking the tree," and this type of query is typically initiated by a DNS server that attempts to resolve a recursive name query for a DNS client.
