Block porn and phishing with ScrubIT filtered DNS

Bookmark This (opens in new window)

A very easy and effective way to block phishing, porn, and other unwanted content is to use a DNS service that blocks address resolution for these sites.

Sorry, I probably lost most of you with that last statement. Let me explain.

DNS, or Domain Name System, is the Internet’s address book. DNS translates web addresses (also e-mail destinations and addresses for other purposes) like http://www.cnn.com into cryptic IP addresses like 64.236.91.22. These IP addresses are what our browsers and e-mail programs actually use to send and receive information. But since names like cnn.com are easier to remember, we use those instead, and DNS does the translation for us without our even having to think of it.

Instead of using your ISP’s DNS, consider using ScrubIT, a reliable DNS provider that “filters” unwanted sites like porn and phishing, so that any wayward clicks in spam or phishing e-mails takes you to a page that says your access has been blocked.

ScrubITScrubIT is free, and it takes only a couple of minutes to set up. If you have several computers and a home router, you can configure your home router to use ScrubIT, which will automatically protect all computers in the home. Similarly enterprises can use ScrubIT as one means for blocking access to porn and phishing.

Simply configure these two addresses as your DNS servers and you’re set: 67.138.54.100 and 207.225.209.66 .

You should not rely upon ScrubIT alone to protect yourself from unwanted events. Practice a defense-in-depth strategy to protect your systems and your information from unauthorized access, disclosure, and harm.

    I do not understand how to configure the DNS for 67.138.54.100 and 207.225.209.66 so that I can use ScrubIt on this computer (Running Vista).
    If I have a computer hooked up to the wireless router, and this computer gets service through the router, is ScrubIt working on here, or can I change something on those (not this computer)
    Is there someone I can call for help? Cost?
    Thank you.

    The ScrubIt website should have instructions for changing DNS settings for all modern versions of Windows, including Vista.

    Some wireless routers can be configured to use ScrubIt, which will then protect all systems on the network, provided they use DHCP to get IP and DNS server IPs.

    I don’t know whether ScrubIt has a live tech support capability – I presume not. But you can always call your cool computer friend or Geeksquad.

    Hope this helps,

    Internet
    filters
    are used to prevent people from surfing where the administrator does
    not want them to go.
    For example, they may install a filter at work to prevent "Cyberloafing". 
    Or a parent may want to install and internet filter in order to keep their kids
    focused on homework instead of surfing the web.  Also, filters are used to block
    porn
    .
