Linux OS

Different Linux distributions use different DNS resolvers (e.g., systemd-resolved, nscd, dnsmasq, or NetworkManager).

To check which DNS service your system uses, run the following command in your favorite terminal/shell application:

ps aux | grep -E "systemd-resolved|nscd|dnsmasq"

You will see the name of the DNS resolver used on your Linux system in the output of this command. It may be systemd-resolved, nscd, or dnsmasq.

If none of those appear, your system might rely on NetworkManager or your browser’s DNS cache.

After you know which DNS resolver is used in your system, choose the correct command for clearing a local DNS cache for this resolver:

Resolver	Command to clear cache
systemd-resolved	sudo systemd-resolve --flush-caches
resolvectl	sudo resolvectl flush-caches
nscd	sudo systemctl restart nscd
dnsmasq	sudo systemctl restart dnsmasq
NetworkManager	NetworkManager sudo systemctl restart NetworkManager

You can check if the cache was flushed successfully using this command:

$ sudo systemd-resolve --statistics



If you see a zero by the Current Cache Size, you have successfully flushed your system's cache.
