The root zone file is a critical part of the Domain Name System (DNS) infrastructure. It lists all the top-level domain names (.com, .org, .net, etc.) and their corresponding authoritative name servers. This file is maintained by the Internet Assigned Numbers Authority (IANA) and is essential for resolving domain names to their corresponding IP addresses.
The domain name itself is located within the Domain Name System (DNS), which is a hierarchical system used to translate human-readable domain names into IP addresses that computers use to identify each other on the network. The DNS is distributed across numerous servers worldwide, with root servers at the top level, followed by TLD (top-level domain) servers, and authoritative name servers for individual domains. When you enter a domain name into a browser, your request is processed through these servers to locate the corresponding IP address.
it is just a delimiter. Domain names are human friendly form of IP addresses which are numerical(binary) & contain delimiter dot(.).
