Put another way, the client does a form of delegation in a recursive DNS query. It tells the DNS resolver, “Hey, I need the IP address for this domain, please hunt it down and don’t get back to me until you h
What is recursive DNS? A recursive DNS lookup is where one DNS server communicates with several other DNS servers to hunt down an IP address and return it to the client. This is in contrast to an iterative DNS query, where the client communicates directly with each DNS server involved in ...
The default DNS server (BIND) access control list forallow-recursionis set tolocalnets; localhosts;1 On RHEL7 and RHEL8 up to 8.1, the system default is to allow recursive query from any host.allow-recursionoption, which allowsanyhost to perform recursive query, is included innamed.conftemp...

If there were no changes being made in DNS, and there were not multiple views of a zone from different physical locations, in theory one should be able to re-query the same name servers and get the same answers as those in the cache dump. Given there are many different configurations ...
Recursive DNS queries generally tend to resolve faster than iterative queries. Why? Because the Recursive DNS server caches the final answer to every query for a certain amount of time (TTL). Tasks of the Recursive DNS server: Checks if the IP address is stored in the cache memory ...

You can test to see if Recursive DNS is configured on your server: Using cmd line on your local computer enter: nslookup google.com 'your server IP' If you get an error "Query Refused"; Recursive DNS is not enabled. If you get a 'Time Out' please try again, if you get DNS ...
recursive query:递归查询 recursive definition:递归定义 recursive relation:递归关系 词根词缀及记忆方法 词根:“recur-”表示“再次发生、重复”。 后缀:“-sive”是形容词后缀,表示“具有……性质的”。 记忆方法:结合词根和后缀的意义,将“recursive”理解为“具有再次发生或重复性质的”,进而联想到递归的“自我调...
Under normal circumstances, a name server willrecursively querythe Internet looking at certain name servers until it finds the answer it is looking for. 借助 这些名字服务器的帮助,一台名字服务器能对整个Internet进行查询。 ParaCrawl Corpus forwarders -- This sets the list of DNS hosts that will be...
