--fast-dns-retry=[<initial retry delay in ms>[,<time to continue retries in ms>]]

Under normal circumstances, dnsmasq relies on DNS clients to do retries; it does not generate timeouts itself. Setting this option instructs dnsmasq to generate its own retries starting after a delay which defaults to 1000ms. If the second parameter is given this controls how long the retries will continue for otherwise this defaults to 10000ms. Retries are repeated with exponential backoff. Using this option increases memory usage and network bandwidth. If not otherwise configured, this option is activated with the default parameters when --dnssec is set.
