Browser(application) level:
For Google Chrome/Chromium, open the link below:
chrome://net-internals/#dns
and click “Clear host cache“
For Firefox, open the link below:
about:config
then click “I’ll be careful, I promise!“,
and find network.dnsCacheExpiration, set its value to 0 (create one if it didn’t exist).
Now the cache should be flushed, and set network.dnsCacheExpiration back to 3600, or you the cache will not work at all.

ipconfig /flushdns

sudo /etc/init.d/dns-clean restart
sudo /etc/init.d/nscd restart
sudo /etc/init.d/dnsmasq restart

- macOS (> v10.5):
dscacheutil -flushcache
