    Google DNS works different than other DNS providers, offcourse this misery or magic has its privacy issues.

    In stead of quering a request, Google uses a caching mechanism.

    Yep you guessed it builds up a database of most searched sites.

    Speed implications
    Therefore Google is therefore (substantionally) faster than most other DNS-ses

    Downside is that when you have a request for a non-cached website, you have a fair chance that Google does not reply in time. Compared to Open-DNS their no reply rate in time is substantionally higher.

    Security implications
    When you use Google (which has its IP blacklist) and use Open DNS (which has its blacklist) you have two data bases which are checked. So theoreticcally any DNS other than Google (when using Google search) is better than Google.

    combining IP blacklists
    We opted for speed and use Google DNS + Google Search. In Chrome you only have an icon when you add Site Advisor for Chrome and Wot for Chrome (in stead of loosing a complete menubar like in IE). WIth PrevX Safe Online we use 4 IP blacklists in this sequence
    a) Google SEARCH
    b) WOT
    c) PrevX Safe On line
    d) McFee Site Advisor

    Hi Kees, are you sure Google DNS has an IP blackist? I couldn't find any reference to use of such a list.
    I've looked at these links:
    http://code.google.com/speed/public-dns/
    http://code.google.com/speed/public-dns/docs/performance.html
    http://code.google.com/speed/public-dns/docs/security.html

    That's actually the only reason I moved to Norton DNS from Google DNS.

    Nope, You are quiet right - twice
    a) Google DNS does no checking on IP
    b) Google search does domain checking no IP blacklisting (domain checking is more granular)

    My bad, sorry

    No Norton product does this.

    It must be because of
    BetaNews is not blocked anymore.

    I doubt Google DNS will block doubleclick.net :D http://community.norton.com/t5/Norton-DNS-Public-Beta/Blocking-Doubleclick-net/td-p/238356

    Interesting topic :thumb:

    I'm also testing Norton DNS (no NIS or stuff like that here) for the past week and so far so good, no complains at all... except they don't have a Privacy Policy currently...

    http://community.norton.com/t5/Norton-DNS-Public-Beta/Privacy-Policy-Details/td-p/236315

    BTW, i also confirm BetaNews is not blocked anymore... i find this service most usefull for newbies, feedback i'm getting is also most positive. And ya, althoug i don't have WOT extension installed in my PC it provides an "extra" layer of security... sometimes Norton blocks a page, other times it's WOT (WOT goes beyond the phishing / malware backlists Norton DNS uses), sometimes both... and so far no FP's...

    Must have been another temporary block. Softpedia was blocked before http://community.norton.com/t5/Nort...rton/Softpedia-website-is-not-safe/m-p/188629

    Softpedia is green again.

    For as long as I have been using Norton Safe Web products brothersoft.com has been blocked. I see that they have changed the rating to Caution. http://safeweb.norton.com/report/show?url=brothersoft.com&x=0&y=0

    For me, it is Norton DNS. In my personal tests with fresh links from that day:

    Norton 6/10 Blocked
    ClearCloud 4/10
    COMODO 2/10 Blocked
    Google 2/10 Blocked
    OpenDNS 1/10

    6/10 may not seem like the best, but proactively it is great :thumb:

    Alan, when Norton DNS blocks something, do you get a message of some sort?

    I'm asking because I have not got any messages about sites being blocked from Norton DNS.

    It could also be that my surfing is quite conservative (or that some of the ad/image blocking in force prevents me from seeing the message).

    Good morning Vasa, yes you do indeed. It gives you a link to a report of all threats found, and a link to exit the site. I rarely have something blocked unless I am purposely going to bad links (MDL for example), I am pretty conservative as well.

    Between my 200,000 entry host file, and Norton DNS, I rarely visit malicious sites anymore.

    Cheers, have a good day :thumb:

    Thanks!

    By the way, I don't use a hosts file but I've got the WOT extension for Chrome. The only time I visit a "new" site is via a Google search. So the WOT rings help out there.

    Oh yeah, although community-biased by some standards it is a great tool to have. There was one I ran across for Chrome and Firefox not long ago, that combined both WOT and SiteAdvisor, only problem was you had to actually be on the site to see the rating.
