Domain Name System (DNS) functions like an internet phonebook, translating human-readable domain names into IP addresses. This system allows users to access websites without memorizing numerical addresses. DNS caching improves the browsing experience by storing information about frequently visited sites, enhancing load speeds. Still, DNS cache can become corrupt, leading to slow internet connections or loading issues. Flushing the DNS cache can remedy these problems and is manageable on Linux systems with the right commands and permissions.
DNS translates human-readable domain names into IP addresses, allowing browsers to render websites instead of requiring memory of IP addresses. Without it, navigation would be cumbersome.
The DNS cache stores records for frequently visited websites, enabling faster loading. However, it can become corrupt, leading to slow connections or issues loading pages.
When experiencing slow internet speeds, flushing the DNS cache on a Linux machine can help resolve issues. This requires a Linux instance and sudo privileges.
To flush the DNS cache in Linux, one should verify that 'systemd-resolved' is active, check the current cache size, flush it, and confirm the size is zero.
