Moving on, a recursive DNS might already have the IP address you are looking for, stored on its cache for easy access. But if it doesn’t, it will go to the root servers with physical servers located around the globe for redundancy which manage requests for appropriate top level domains like .com if sav25.com is what you are trying to access, or .net of other websites. That top level domain server .com will then contact authoritative DNS which contains authoritative list of IP address with its matching URLs which is updated every now and then, every time a new domain is registered. Once the IP address is retrieved, it sends back to the recursive DNS and then to your computer or browser.
