-------------

ipconfig /displaydns

If you're referring to the ipconfig /flushdns command on a Windows machine, it clears everything* out of that machine's DNS resolver cache. In effect, the machine “forgets” what it's learned from recent DNS queries and will need to query a DNS server to resolve just about anything.

This is a very useful command when you're troubleshooting a DNS issue or making changes to records on a DNS server.

*In fact, this command doesn't necessarily clear everything out. Anything in the machine's local hosts file (located at C:\Windows\System32\drivers\etc\hosts) will remain in the resolver cache. You can confirm this by adding an entry to the hosts file, then running ipconfig /flushdns and ipconfig /displaydns back to back. The latter command lists everything in the resolver cache. As long as no other process slipped in a DNS query between those two commands, the output should include only what's in the file.
