Domains that may not be blocked with OpenDNS domain blocking

1. opendns.com - Otherwise you couldn't change your preferences.

2. .com - Same reason; you may block other TLDs (top level domains) if you choose.

3. overture.com - OpenDNS is a free service. OpenDNS makes money from advertising and we do not allow our ad server to be blocked.

4. yahoo.com - OpenDNS's search results are returned from Yahoo.com. You may block subdomains if you choose, such as mail.yahoo.com. 

Note: Domain blocking is not intended to be a category blocking service, like phishing or adult site blocking. It's intended to give you pinpoint control over what's on your network.
