DNS records are instructions stored in a database within the Domain Name System. Each record provides specific details about a domain, including its associated IP address(es), how to handle requests for the domain, and more. These records ensure that internet traffic is directed to the correct server and manage the routing of emails, the location of servers, and the verification of domain ownership.
DNS lookup is the process used to retrieve the DNS records for a domain. This process involves querying the DNS servers to find specific information about the domain, such as its IP address. There are two types of DNS lookups: forward DNS lookups, which convert domain names into IP addresses, and reverse DNS lookups, doing the opposite.

When you enter a domain name into your browser, a DNS lookup is initiated. The process starts with a query to the Recursive Resolver, which then queries the Root Nameservers. These direct the query to the TLD (Top-Level Domain) Nameservers, which, in turn, point to the domain's authoritative Nameservers. These authoritative Nameservers respond with the requested DNS record, allowing the browser to connect to the correct server using the IP address obtained.
