California Penal Code 198.5 sets forth that unlawful, forcible entry into one's residence by someone not a member of the household creates the presumption that the resident held a reasonable fear of imminent peril of death or great bodily injury should he or she use deadly force against the intruder. This would make the homicide justifiable under CPC 197. CALCRIM 506 gives the instruction, "A defendant is not required to retreat. He or she is entitled to stand his or her ground and defend himself or herself and, if reasonably necessary, to pursue an assailant until the danger ... has passed. This is so even if safety could have been achieved by retreating."

While the OpenDNS name resolution service is free, people have complained about how the service handles failed requests. If a domain cannot be found, the service redirects you to a search page with search results and advertising provided by Yahoo!. A DNS user can switch this off via the OpenDNS Control Panel but will lose content filtering ability. This behavior is similar to that of many large ISP's who also redirect failed requests to their own servers containing advertising. [12]

In 2007, David Ulevitch explained that in response to Dell installing "Browser Address Error Redirector" software on their PCs, OpenDNS started resolving requests to Google.com. Some of the traffic is handled by OpenDNS typo-correcting service which corrects mistyped addresses and redirects keyword addresses to OpenDNS's search page, while the rest is transparently passed through to the intended recipient.[13]

Also, a user's search request from the address bar of a browser that is configured to use the Google search engine (with a certain parameter configured) may be covertly redirected to a server owned by OpenDNS without the user's consent (but within the OpenDNS Terms of Service).[14] Users can disable this behavior by logging in to their OpenDNS account and unchecking "OpenDNS proxy" option.[15] Additionally, Mozilla users can fix this problem by installing an extension[16] or by simply changing or removing the navclient sourceid from their keyword search URLs.

This redirection breaks some non-web applications which rely on getting an NXDOMAIN for non-existent domains, such as e-mail spam filtering, or VPN access where the private network's nameservers are consulted only when the public ones fail to resolve.
