OpenDNS and OpenDNS Umbrella

opendnsI have been using OpenDNS at home to keep the kids from getting onto questionable sites for over a year….

The process is quite simple…  Whatever device is doing DHCP for your home network (your wireless router, or maybe you have a residential gateway)… Just tell it to give out OpenDNS’s  name servers instead of the name servers provided by your ISP…

208.67.222.222208.67.220.220

That alone is sufficient to keep all you

But you can take it a step further…If you set up a free account with OpenDNS, and download and run a client somewhere in your home network (so they know your IP)… Then you can set up filters to block out DNS lookups to specific web site categories, or even individual websites on your home network…r internal devices from  known malware and phishing sites…

It’s not full-proof of course – but it was sufficient to keep my kids out of trouble..

That was… Until one of them got a cell phone, and she figured out that all she needed to do was shut off her Wi-Fi, and access the sites over 3G..

Well… OpenDNS has a solution for that too… OpenDNS Umbrella

The “mobile” service offering –  probably meant for the corporate world – sets up a VPN tunnel between the phone and OpenDNS proxy servers…  And then leveraging that proxy to filter out web sites as above. Cost is $20/year for an individual plan…  

Again, not fail safe… And it does slow down the older phones (Apple 3GS) a bit… But it’s been effective at keeping her out of some sites.

For now any ways…
