No queries are blocked. A DNS server will answer either iterative or recursive queries. However, if you mean in the sense of blocking any type queries in general, BIND offers a "View" option that you can configure what subnets to listen on, however, not with Windows as of this writing....
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. Figure 5.4 shows an example of iterative and recursive queries. This example assumes that none of the...
Recursion in DNS (Domain Name System) is the process of a DNS Server, querying other DNS Server on behalf of original DNS Client. Iteration is the process of aDNS Client, making repeated DNS (Domain Name System) Queries to differentDNS Serversfor name resolution. Recursive DNS Query:In a Re...
The number of iterations or self joins required to execute a recursive database query can be estimated. It will be appreciated that this estimation can be used to plan the execution of the recursive query and can be made in various ways and for various applications. By way of example, an ...

Recursive and Iterative Queries项目 2010/03/04 With a recursive name query , the DNS client requires that the DNS server respond to the client with either the requested resource record or an error message stating that the record or domain name does not exist. The DNS server cannot just refer...

An execution plan for executing one or more iterations of recursive database queries can be generated in accordance with one aspect of the invention. For example, in accordance with one embodiment of the invention, one or more cardinalities (results or size of results, including intermediate ...
