FYI, opennic is far more than just an alternative resolver to OpenDNS. OpenNIC is running an alternative set of roots, with TLDs that aren't agreed to by the regular DNS-managing bodies (like ICANN). That may be fine with you (opinion on ICANN's handling of new TLD's is a subject for another time), but be aware that you're seeing a different DNS with opennic than you would be with OpenDNS or google's 8.8.8.8
