How do we deal with incognito browsing?

[zoomiest]

I just ran a few tests... I got OpenDNS up and working again, and ran some tests to see what it is blocking. Fine.

Then I opened an incognito window in Chrome, and ran the same test, and ... nothing is blocked - even with OpenDNS functioning...

It seems that Chrome pulls a new set of DNS addresses (likely from my ISP), so if my son opens up an incognito window to look at porn, he effectively bypasses everything I have set up.

What is the answer? Buy a desktop software-based filter?

Your best bet is to not use Chrome or Opera which tend to circumvent OpenDNS by using the suppliers' caching servers, but a different browser.

Whatever, there may be fixes available, see e.g.

http://ohryan.ca/2008/12/10/google-chrome-bypasses-opendns-and-how-to-fix-it/  (This option may be different in newer versions of Chrome.)

You'll have to test what works for you.

OpenDNS currently does not enforce safe search. Effectively this means a user can easily access inappropriate content by entering incognito or inprivate modes, searching for anything they want using google, yahoo, or bing, and seeing anything they want by clicking on the image tab. This bypasses most parental control software and parental control routers. I've found three routers that conveniently enforce safe search at the router (I'm not affiliated with any of these in anyway. I'm just a concerned parent doing their homework.):
