Why is a site marked by PhishTank as a phish not blocked by OpenDNS?
A judgment from the PhishTank community about a suspected phishing site is one factor in the decision about whether a site is blocked for OpenDNS users (those who have phishing prevention enabled). OpenDNS gets feeds from multiple sources. As of October, 2006, PhishTank is now one of those sources. PhishTank also may identify a phish website which, for instance, uses IP addresses in its URL, and therefore cannot be blocked at the DNS level. PhishTank and OpenDNS are operated as separate systems.
