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.
DNS propagation is a process that requires time, and you probably wonder what is happening during it. So let’s explain a little bit more about it.
DNS propagation explained
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.
Having an online business pushes us to get the best out of technology to increase our chances of succeeding. Every network protocol, software, hardware, or tool can become a key component in our strategy if we know how to utilize its possibilities.
That said, let’s talk about Backup DNS (Secondary DNS) as a first step for understanding its benefits.
What’s Backup (Secondary DNS)?
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.
