A recursive DNS server is a specialized server designed to process queries by name servers. When a client sends a query to a recursive server, it goes through a series of steps to find the answer. First, the recursive server checks to see if it has the answer to the query in its own cache. If not, it will send requests to other name servers until it finds a solution. Once a reply has been found, the recursive server will cache it for future requests and return the answer to the client. Recursive DNS servers are essential for providing an efficient way to resolve DNS queries quickly. Check out the detailed guide on how the recursive DNS server works.
