OpenDNS Search PageI am intrigued by OpenDNS business model. OpenDNS is a startup which offers DNS service to any user accessing the internet. DNS is normally a hidden service. Yet OpenDNS carved out a business model which is very viable. But first how do you benefit as an user?

OpenDNS aims to makes your internet experience safer, faster and smarter. In plain English it will warn you of phishing sites (which anyway Internet Explorer 7 and Firefox will do too. Also it will automatically correct small spelling mistakes and guide you to the proper site.

In case where it is not sure about the site you want to go to it will present you will a list of alternatives. This is where it earns revenue. It will also add advertisements to these pages.

I doubt that it can really make your DNS access faster. In most cases your ISP is more likely to provide faster results. In case it doesn't you can always use a local caching DNS server for free. It tremendously improves performance without having to send your information to OpenDNS.

OpenDNS will know all the sites you are visiting and your browsing patterns. It tracks which items you are clicking on the search results. How will they use this data? This data is a goldmine to advertisers and I am sure they will make a fortune by simply selling this data.

Marshall from TechCrunch thinks they do not have a viable business model. I disagree. Misspellings are much more common than anyone of us would care to admit. Serving ads on misspellings can provide significant revenue as you have dedicated users 24/7. Each user you convert to using your DNS is an user who allows you to correct his misspellings all the time. I have no doubt about the viability of their business model. The cost of running such business is small. You simply have to buy servers hosted in different countries.

My concerns are elsewhere. If OpenDNS is hacked, it will pretty much instantly disable internet access to all of their users (unless they change DNS manually). Worse, users may be directed to malware or phishing sites en masse. You cannot even trust your banking sites with proper url. The control you are giving to a single company is way too much in my humble opinion. Thanks, but no thanks.
