Service RNIDS What is DNS for The main role of DNS is to facilitate the process of accessing web pages and other resources on the Internet . When a user enters a desired domain name into a browser DNS provides the corresponding IP address associated with that name. in correctly routing data to servers. When a user requests information via a domain name DNS sends the request to the appropriate server which then returns the requested information to the user's device. How does DNS work in the background In a typical DNS query four servers cooperate to deliver an IP address to the client Local DNS server ROOT server TLD TopLevel Domain server i Authoritative server.
DNS system how it works How the DNS system works The DNS resolver also B2B Email List known as the DNS recursor represents the first point in a DNS query and represents the client side of DNS. The recursive resolver acts as an intermediary between the client and the DNS nameserver. After receiving a DNS query from the client the recursive resolver will either respond with cached data or send the request to the servers according to the hierarchy first to the ROOT server then to the TLD TopLevel Domain server and finally the last request to the authoritative server.
Receiving a response from the server containing the requested IP address the recursive resolver sends the response to the client. During this process the recursive resolver will cache the information it received from the authoritative nameservers. When a client requests the IP address of a domain name recently requested by another client the resolver can bypass the process of communicating with nameservers and simply deliver the requested record from its cache to the client. This entire process takes place in milliseconds which allows users to quickly and efficiently access pages and resources on the Internet. What is DNS caching DNS caching means storing data closer to the client requesting information so that the DNS query can be resolved earlier.
