Why is a domain (URL) not resolving with OpenDNS?
If you're using OpenDNS, and a domain (URL) is not resolving, you should see the OpenDNS search results page. That indicates a possible DNS problem. If you are getting a "Page not found" error message in your browser, that is not a DNS problem. If you are seeing the OpenDNS search results page for a domain you know exists, the likely causes are one of the following:
- The domain's DNS has problems. To date, this has been the most common result of our investigations. If you are the domain owner, please double-check your nameservers.
- The domain was recently moved from one webserver to another, and the TTL (Time To Live) has not expired. Before moving a domain, please lower your TTL to the minimum available, so all nameservers know to check often for updates.
- There is a problem with an OpenDNS server. While we expect this to be the rarest of the three possibilities, we do want to be sure, so please contact us with details so we can investigate.
