DNS records are simple instructions that are associated with a particular domain name. In the DNS zone, the full collection of entries is compiled in a zone file. All of this information is stored on the authoritative DNS server for the relevant domain name. Each record serves a certain purpose. As a result, they are all extremely important for the domain’s proper operation.
In our article, we will see several DNS terms that will assist you in managing your domain name as effectively as possible. So, let’s begin.
The Domain Name System (DNS) is a global system that connects domain names to IP addresses. It has a multi-level hierarchical structure that is decentralized. It is quite useful and beneficial to people. If DNS didn’t exist, we have to input and remember every IP address on the web pages if DNS didn’t exist, which would be difficult. So, with the Domain Name System, we can employ easy-to-remember domain names and the page will load. It’s really simple.
The Host command is a built-in utility software with a command-line interface (CLI) for DNS probing. You could find it pre-installed on most Linux distros like – Ubuntu, Linux Mint, Red Hat, or macOS. It serves perfectly for network diagnostics. In addition, the most common use of host command is to complete DNS lookups and check different information about a domain name and its DNS records.
It is a very light and quick tool that can give you data about different DNS records, such as A, AAAA, MX, NS, SOA, and more. In addition, it can provide you with information for the host, for instance, its IP addresses or check nameservers.
