DNS propagation is a crucial process whenever you make changes to your domain’s DNS settings, such as updating nameservers or modifying DNS records. This process can take time, as DNS changes need to spread across multiple servers worldwide. In this article, we will explain more about this process, the factors that influence its duration, and what you can do to optimize it.

What is DNS Propagation?

DNS propagation refers to the period it takes for DNS changes to fully update and take effect across the internet. When you modify DNS settings, those changes are not instantly applied everywhere. This delay occurs because DNS servers around the world cache information for efficiency. As a result, the propagation time can vary from a few minutes to up to 72 hours, depending on several factors.

What does DNS downtime mean? 

DNS downtime, also known as DNS outage, is the time during which the DNS is unavailable. You already know how important the resolution procedure is for gaining access to your domain name. The procedure of translating it to its IP address will be impossible if DNS fails. As a result, your website will be unable to be found, and its content will be unavailable.

The whole complicated Domain Name System has different DNS record types. Without them, this system will not be able to function. Why they are so important and what are their primary purposes we are going to see today in this article.

DNS resolution – Definition

The DNS resolution is a fundamental process that resolves a domain name to its IP address (IPv4 or IPv6). Without it, the entire Internet would work in a completely different way. However, it occurs behind the scenes because regular users don’t even notice that it is happening. People are used to typing a simple domain name, and the desired website is loaded in their browser. However, the user’s DNS query is actually traveling through several separate servers until it receives a full answer.

GeoDNS – What is it?

You can find GeoDNS, also called global traffic director or only traffic director. Don’t get confused. They mean exactly the same thing! It represents a very effective technique for optimizing the incoming traffic of a domain via geographical-based routing.

If we compare the traditional DNS service and GeoDNS service, we should point out the main difference. The traditional DNS servers store an identical IP address for a particular domain. On the other hand, GeoDNS includes storing multiple IP addresses based on the location. In addition, it is an alternative for cloud-based load balancing. As a result, the overall performance of your network is going to be improved.
