Flushing your DNS

[Corey]

XP And Below:
1.) Go to start->run.
2.) Type in "cmd" without the quotes.
3.) At the command prompt type "ipconfig /flushdns" again without quotes.

Vista:
1.) Click on start->All Programs->Accessories
2.) Right click on the command prompt and pick run as administrator.
3.) At the command prompt type "ipconfig /flushdns" no quotes.

Linux:
1.) Open a root terminal or use sudo (in ubuntu or similar systems) with the following command:
- "/etc/rc.d/init.d/nscd restart" (without quotes)

Mac OSX Leopard:
1.) Use the following command in a terminal window:
- "dscacheutil -flushcache" (without quotes)

Mac OSX 10.5.1 and before:
1.) Use the following command in a terminal window:
- "lookupd -flushcache" (without quotes)

This will flush your DNS and will solve a lot of issues with your computer caching the wrong information.

Thought i'd extend this about to cover the non-windows folk:

For Mac's
Use a shell to run the command
lookupd -flushcache

For Linux
Use a shell or terminal to run
/etc/rc.d/init.d/nscd restart

It's good to see a tutorial on this. People might actually search for this thread before asking how to flush their DNS!

 

[Jesse]

This will help people...
Maybe this thread should be sticky? since many users can try this before they post a new thread regarding their site not loading, etc.

Thanks Corey.

You should probably sticky this as Jesse Said.

DNS Means what?
Sorry i don't know this.

 

[lamplock]

DNS is domain name servers, they are the means we all navigate the internet by; they hold the ip information for each site (eg convert bbc.co.uk to 212.58.224.131). For website developers they are important because as information is updated we need DNS servers to point to the fresh content rather than the old. This will be updated periodically, but it is sometimes useful to flush the DNS to verify all routes.

Sorry, didn't see your post. I added Linux and both Mac versions to Corey's.

This thread does not appear anywhere near the top of the search results when you search on 'flush DNS'. Anyway to force a top result?
