OpenDNS is an enhanced DNS resolver open to the public (as of today) and free to use. It contains a number of enhancements such as typo correction and phishing protection.
It is also fully configurable for the end users, so individual features can be turned off at the users’ discretion.
I’ve also posted a comment on CircleId explaining why OpenDNS is not Sitefinder 2.0
(By way of quick explanation to the layman, there are three kinds of nameservers that affect your life:
- Root nameservers: which top level domain registries operate, such as the root nameservers for .com or .ca
- Authoritative nameservers: for individual domains. This is the business easyDNS is in: answering DNS queries authoritatively for its member domains.
- Recursive nameservers or resolvers: these nameservers find out DNS info on behalf of its users. Usually these are transparent to end-users and supplied by ISPs, often via DHCP. OpenDNS is now in this business. )
