OpenDNS Porn Blocking

I learned something new from Brian Kreb’s Security Fix found at WashingtonPost.com. In today’s entry he writes that OpenDNS has added a voluntary feature to block porn.
OpenDNS is a free DNS service that purports to be faster and more reliable than the ISP DNS you are probably using by default. Also they add in some anti-phishing and anti-typo features to protect their users. They make money by hijacking the result if you type in a non-existing webpage such as www.asdfasfdasdfasfasdfasfd.com.
Anyway, if you register your IP address with OpenDNS, you can sign up to have those dns requests checked by their St Bernard implementation.
I set it up this afternoon. It was easy to add their DNS servers into my Linksys Router (sveasoft talisman firmware), but I didn’t see a way to set up DDNS updating without putting a DDNS updater on my desktop. I would have preferred to do that on the router.
This is a good free setup to stop unintentional access. If you’ve got people trying to get around it, you’re better off having a filtered ISP or running a proxy server that is physically protected (along with the cable modem) to prevent bypassing.
