Flush DNS cache Jump to heading
1. Clear OS-level DNS cache Jump to heading
On Mac OS, run this in the terminal:
sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder
On Windows:
ipconfig /flushdns
2. Clear DNS cache via Chrome Jump to heading
Go to chrome://net-internals/#dns and click Clear host cache.
This button sounds like it should clear the OS-level cache, but my experience just doing this isn’t enough by itself.
3. Close existing server connections Jump to heading
Go to chrome://net-internals/#sockets and click Flush socket pools.
Then reload the page you’re testing and you should see the DNS lookup again, as well as the time spent on establishing the TCP connection.
