DNS is a network of name servers with a tree-like structure that makes them work together to resolve domain names to their IP addresses. They do it, so billions of users can enjoy the Internet the way it is right now. One of the key elements that allows it is the DNS delegation. One higher-level server can delegate a part of the namespace to a lower DNS name server, and that way, it became the Primary DNS server for the zone it got delegated.
Domain name system (DNS) records look like small components, but their role is really important. Those small pieces of data accomplish specific purposes. They are key for the Internet’s performance and its permanent interaction with domains.
Here you have what is important to know about the DNS TXT record.
What is the DNS TXT record?
TXT or text records are the ones that have text format data for external sources. This means sources outside domains like yours. Usually, on these records, you can find general domain information but also key data required for validation. Through TXT records, ownership of a domain can be verified, data for e-mailing can be validated, etc.
This type of record was created for human-readable notes for administrators. But since text has become a common language for machines too, it is readable and understandable for both. This advantage makes DNS TXT records a vital tool for administrators to give instructions to machines through entering text into the DNS.
The domain name system (DNS) executes different key processes for the Internet to work properly. Those tasks could not be resolve without DNS records. There are different DNS records, and each has different functions. Let’s talk about DNS NS record.
What is DNS?
The DNS (Domain Name System) is a decentralized system with a strict hierarchical structure for naming devices and services on the Internet and private networks. It is an essential part of how today’s global connected network, the Internet, works.
It is responsible for directing queries for a particular domain name, like goolge.com, through all the nameservers of different levels that know where the imputed domain name is located. It helps us by answering our domain name queries with the IP address of the host (IPv4 or IPv6 or both).
It also finds services, verifies them in different ways, links different domain names, points to servers, redirects, and, in general, makes our lives a lot easier when using the Internet.
Starting learning about DNS, you will have many challenges. It is hard to understand the matter. The best way to understand it is in bite-size chunks. This is why we want to show you the first and most commonly used DNS record types. They are easy to understand, and you will probably start using all of them from day 1. So A, AAAA, CNAME, NS, SOA, MX, PTR, and TXT records are a must.
