How to speed up the DNS propagation?

DNS propagation is a fundamental concept in the world of the internet, crucial for both web developers and everyday users. In this article we will dive into what it is, why it takes time, and practical steps to speed up the process.

What is DNS Propagation?

DNS propagation is the process by which the updated DNS records of a domain are spread across all the DNS servers worldwide. Essentially, it’s the period during which updates to a DNS record (such as changing the IP address linked to a domain name) take to be fully updated across the internet’s web servers.

When you make changes to your DNS records, like switching hosting providers or moving to a different server, those changes aren’t immediate. Every server that caches DNS information needs to update its cache, leading to a propagation period.

What do you need to know about TTL?

TTL: Definition

Time-to-live (TTL) is the value that specifies the time period or number of hops that a data packet must travel to be alive. Either across the network or in the memory cache. It will be terminated when this timer expires, or the data packet reaches its hop limit. Data packets are not all the same; they vary in size and shape, but each has a different TTL. The amount of time data packets should live in a device to perform their missions should be determined.
