The topic of our post today is the DNS terms. We will explore the primary six that every beginner in the Domain Name System should be aware of. So, let’s start and take a deep look at the most essential ones.
The DNS zone is the DNS namespace’s administrative partitions. Each one is managed by a different DNS administrator, which makes the system decentralized. Many people mistakenly believe that a DNS zone and a domain are the same things, however, this is not the case. There is no discernible difference if a domain has only one DNS zone. It can, however, have more DNS zones, which will be distinct.
An IP address, or Internet Protocol address, is a number that identifies network hardware that is linked to a network. A device with an IP address can communicate with other devices through an IP-based network such as the internet.
IP addresses contain crucial location data for locating and identifying devices. They’re also required for devices to communicate and share data via a network.
DNS records are text files that contain details about the Domain Name System. Every domain has a varied number and variety of DNS records. So, they denote distinct domain entities and situations. One could, for example, point to an IP address (A or AAAA record), while another could show a specific service, such as the email server that receives emails (MX record), and so on.
The domain name is yet another essential term. It’s a text string that’s used to map an IP address. We use it to visit websites by writing their names instead of their numerical addresses, which are known as IP addresses. For example, instead of typing 18.104.22.168, we can type example.com. So example.com is the domain name.
The process of searching DNS data is known as DNS query. It’s usually an IP address (A record or AAAA record), but it could also be a DNS record for a domain name. Users initiate DNS queries whenever they want to access a specific website. The DNS resolver (Recursive DNS server) receives the DNS query and queries the Authoritative DNS servers for the required information.
The purpose of a DNS server is to maintain the Domain Name System (DNS), which connects Internet domain names to IP addresses. There are two types of DNS servers: Authoritative name servers and Recursive name servers.
The zone file of a specific zone is held by Authoritative name servers. They are able to respond to DNS queries. All Authoritative name servers for each domain, such as TLD servers and Root servers, fall within this category.
The Recursive name servers are in charge of finding the answer to the DNS query. So they go around querying various servers until they get a response.
To sum up, it is essential to know the fundamental DNS terms if you are now entering the DNS world. They serve as the foundation for everything else. In addition, they will undoubtedly assist you in improving your DNS management. So, don’t waste any more time, and take advantage of them!
