How to clear DNS cache on dd-wrt?

My router is flashed with dd-wrt which uses the dnsmaq daemon.

About dnsmasq? 

dnsmasq is a lightweight DNS, TFTP and DHCP server. It is intended to provide coupled DNS and DHCP service to a LAN. Dnsmasq accepts DNS queries and either answers them from a small, local, cache or forwards them to a real, recursive, DNS server. 

To flush out dns cache the dnsmasq daemon has to be restarted.

Login to the router terminal and run commands

# stopservice dnsmasq

# startservice dnsmasq
