Hi, I don't use OpenDNS, because it allows DNS recursion, which can slow down lookups potentially. I allow recursion, but only for trusted IPs. I use SimpleDNS for Windows on a 2012 R2 Windows virtual server. Each to their own I guess.

Hi: Anyone used Open DNS on a business network? Currently our internal DNS servers resolve external queries by just going to the root servers and working from there, but our security guy has it in his head that OpenDNS is a better way to go for some reason. In looking at their web site they do offer some business services that report to block malware by blocking its DNS lookups (until malware writers use IP addresses directly or point to another public DNS server I guess that would work well.) I know quite a few people that use OpenDNS at home and I think it works well, I’m just wondering if its really more secure than just going the route we go today. Thanks.
