It appears that the page http://setup.nortondns.com/ hasn't been updated yet to recognize the new IP addresses. Although the page states that your computer is not using Norton DNS, if you have configured the IPs in your DNS settings, you should see a block page when attempting to visit a malware site.
We'll be making updates to the ConnectSafe website to address this issue in the future.

The Norton ConnectSafe Team
