Visit http://welcome.opendns.com/ to test your new settings.

You should see the Welcome page from OpenDNS, as shown below.

Troubleshooting

If you see the Oops page, please try two more tests, in case the Welcome page was improperly cached.

1. First, visit our demonstration site internetbadguys.com. If you were successful in switching to OpenDNS, it should be blocked as a phishing site. Otherwise, it will tell you that it's a demonstration site.
2. Second, make a deliberate typo in the TLD, like craigslist.og and see if it resolves to craigslist.org. If you are using OpenDNS, you will be taken to the classifieds site. If you are not, you will get your default browser error page.

Still not working? You may need to restart your web browser and/or router.
