Description: Browser DNS prefetching is a technique that resolves DNS queries before a user clicks on a link. This means that by anticipating the user’s action, the browser can proactively look up the IP address corresponding to a domain. This technique improves the loading speed of web pages, as it reduces the waiting time that would normally be required to resolve the domain name at the moment of clicking. DNS prefetching is based on the idea that many users tend to follow links on a web page, so the browser can predict which links will be selected and perform DNS resolution in the background. This functionality not only optimizes the user experience by making pages load faster, but it can also reduce the load on DNS servers by distributing queries more efficiently. In the context of web technologies, prefetching can be particularly useful, as it allows developers and website administrators to enhance the performance of their applications and services, ensuring that DNS resolutions are carried out quickly and effectively.
