Iterative DNS query

An iterative DNS query is a type of DNS query where the DNS server responds with the best answer it can find, based on the information it has available. If the DNS server does not have the requested information, it will return a referral to another DNS server that might have the information. What's the difference between an iterative and recursive DNS query? The difference between an iterative and recursive DNS query is that a recursive query will continue to query DNS servers until it either finds the answer or reaches a DNS server that doesn't have any further information. An iterative query, on the other hand, will only query each DNS server once and then stop.

What are the three 3 types of DNS queries?

The three types of DNS queries are:

1. Recursive queries
2. Iterative queries
3. Inverse queries

1. Recursive queries are queries where the DNS server will attempt to resolve the query itself. If it is unable to resolve the query, it will return an error.
2. Iterative queries are queries where the DNS server will return a list of DNS servers that may be able to resolve the query.
3. Inverse queries are queries where the DNS server will return the domain name for a given IP address.

What is a DNS recursive query? DNS recursive queries are used to resolve DNS names that are not already in the local DNS server's cache. When a local DNS server receives a recursive query from a client, it will send the query to a root DNS server to resolve the name. If the root DNS server cannot resolve the name, it will send the query to a DNS server that is authoritative for the domain.

What is iterative and recursive?

Recursive routing is a process whereby a router uses information from the routing table to select the best path to a destination. The router then forwards the packet to the next hop on the best path. If the next hop is the final destination, the router delivers the packet to the final destination. If the next hop is not the final destination, the router forwards the packet to the next hop and the process repeats itself until the packet reaches the final destination.

What are the two types of DNS?

The two types of DNS are the Domain Name System (DNS) and the Windows Internet Name Service (WINS). DNS is a hierarchical distributed database that stores information about domain names, while WINS is a Microsoft proprietary service that resolves NetBIOS names to IP addresses.
