Web Content Filtering with OpenDNS (Linux Journal)
Linux Journal takes
a look at OpenDNS for content filtering. "OpenDNS is a free
service that enables you to block content you deem inappropriate at the DNS
level. There's no need for any proxy configuration on either the client or
the server. All you have to do is arrange for your servers and clients to
use the OpenDNS DNS servers instead of the DNS servers provided by your
Internet provider. Once that is done, if users try to access a Web site
that provides inappropriate content, they are redirected to an OpenDNS Web
site that tells them the site has been blocked and why."

Wouldn't any persistent kid figure out the ip address to avoid being blocked?
Might still be useful Posted Mar 3, 2009 22:09 UTC (Tue) by dwheeler (guest, #1216) [Link] Just having an IP address isn't enough on many websites; a lot of sites have shared IPs. And in any case, the goal is probably mild and easy deterrence for the non-technical person, not perfect protection. Many kids would just move on.

So you need to add this IP to /etc/hosts or %system32%\drivers\etc\hosts.
Much difference, yeah.

I think the main idea is to protect the user from sites they don't want to access, such as spam and malware, not to block users against their wishes.

No. Maybe on a silly home network (about which noone cares), but not on a corporate network. On a Corporate network you are required to use the provided internal DNS servers. At the network edge/gateway DNS traffic from any other hosts is filtered out - so if you don't use the provided DNS servers you get no DNS service. The only way to get around them is to tunnel out with a VPN provided that will not be filtered.

Which is why one cannot browse to IPs on our network unless they have been whitelisted.
