Note: Refreshing a domain can take up to 20 seconds.

For domain owners:

OpenDNS gives you unique insight and control into how OpenDNS resolves your domain with OpenDNS CacheCheck. If you are moving a domain from one DNS host to another, CacheCheck can help you make that transition smoother. In effect, you tell OpenDNS to "refresh now," ahead of Time-To-Live (TTL) expiration. Note: OpenDNS can cache a domain for full time-to live (TTL).

For website visitors:

If you visit a domain and find that it's not resolving, CacheCheck is a way for you to learn more about why that might be happening. In some cases, you can help fix the problem even though you don't control the domain itself.
