How Do I Flush a DNS cache?
This article was written originally to help those who could not access Photobucket after a DNS attack, but is retained here, to help anyone who needs to flush their DNS cache.
Because of the nature of dns, a dns problem (due to a technical glitch or hacking), can take up to 48 hours to resolve, and resolution relies on your Internet Service Provider (ISP) fixing things on their end, so your first course of action is to speak to them.
Then, you may wish to ensure that things are clear on your end, by flushing your DNS cache:
How do I flush my dns cache?
- Click on Start--> Programs --> Accessories --> Command Prompt.
- A little black command prompt opens. In it type: ipconfig /flushdns
- Hit return. You should see the lines: Windows IP Configuration. Successfully flushed the DNS Resolver Cache.
- Try accessing Photobucket again.
- You might try to restart your computer, just in case.
Mac users (except Leopard): Finder windows Applications --> Utilities --> Terminal and type in lookupd -flushcache, then hit return.
Leopard users: Open a terminal window and type in dscacheutil -flushcache, then hit return.
