For example, we will look at how a Web browser functions. There are a number of applications that need to initiate a DNS reference call. If the network gives access to the internet, the system’s users will also get access to a DNS server for internet domain names. Networks run their own DNS servers to record the mappings between hostnames and IP addresses within the private domain. The command’s name derives from “name server lookup.” Its purpose is to query the default domain name server and return information on those mappings between domain names and IP addresses. Nslookup is a networking utility that is available at the command line of any computer that has a network card. DNS reconciles between these two addressing standards.

The devices that pass data around don’t understand domain names – they deal with IP addresses. Instead, it travels over IP-based networks. The Web doesn’t have its own transport system.

The domain name is a concept of the World Wide Web. This is a service that maps IP addresses to domain names. Now, only your computer will use Cloudflare DNS while the rest of the devices will still use Google DNS.DNS is short for the Domain Name System. However, on top of that, if you change the DNS server on your local computer to let’s say Cloudflare DNS, then these settings will override the DNS settings of the router. If you change the DNS server on the router to let’s say Google DNS, then every device connected to the router will automatically start using Google DNS as the DNS Server. But what happens when you change the DNS server on your local machine or the router? Which DNS server gets the priority? Well, it’s easy. By default, we use the DNS servers provided by our ISP (Internet Service Provider). Now, before we get to the process, it’s important to understand the priority of DNS servers. You can do it natively through the command line or with the help of third-party apps. You have set up a new DNS server on your machine and you have no clue whether it’s working or not.
