OpenDNS
By admin on Dec 31, 2008 in freebies, general
OpenDNS is a free, closed-source, DNS resolution service.
OpenDNS provides the following recursive nameserver addresses for public use, mapped to the nearest operational server location by anycast routing:
- 208.67.222.222 (resolver1.opendns.com)
- 208.67.220.220 (resolver2.opendns.com)
OpenDNS offers DNS resolution for consumers and businesses as an alternative to using their Internet service provider‘s DNS servers. By placing company servers in strategic locations and employing a large cache of the domain names, OpenDNS usually processes queries much more quickly, thereby increasing page retrieval speed. DNS query results are sometimes cached by the local operating system and/or applications, so this speed increase may not be noticeable with every request, but only with requests that are not stored in a local cache.
Other features include a phishing filter, domain blocking and typo correction (for example, typing wikipedia.og instead of wikipedia.org). By collecting a list of malicious sites, OpenDNS blocks access to these sites when a user tries to access them through their service. OpenDNS recently launched Phishtank, where users around the world can submit and review suspected phishing sites.
