Strict filter only search engines

    Yes, in software based content filters this is possible. However, OpenDNS as DNS service does not know about URLs, images, web pages, videos or other objects. They just see domain names from your DNS queries. And the strict settings is a parameter appended to the URL, not the domain name.

    Thanks so I assume that it is then not possible through the OPENDNS functionality to limit what Images are displayed?

    With a DNS service like OpenDNS you can block only domains, because this is the only information you send to them. A DNS service doesn't know about images, webpages, videos, music or any other such web objects.

    That said, if particular images are hosted on a certain domain, you can block these images by blocking this domain. Not more and not less.

    So can opendns set up a keyword blocker? It is only dealing with domains. For example, if I want hookers and cocaine to be blocked and I search for those words in Google, Google will return the search result in the URL. It will look something like. Www.Google.com/search=hookers+cocaine5788&%$ so if you set those words to be blocked and it detects then in the URL... Problem solved. That would work right?

    Opendns only sees www,google.com (domain name) and not the complete url including your keywords. So no it will not work as you described.

    This has come up before. Why can‘t OpenDNS sense that a Google search is happening and append the 'safe search'= true statement to the end of it? It's already acting as a proxy.

    Because OpenDNS does not act as a proxy, but as a recursive DNS service, they don't see any URLs and can't append anything to them.  (This may be different for Umbrella/Enterprise versions.)  Why did you think that OpenDNS acts as a proxy?

    OK Rotblitz, that's fair. I was mistaken. In the meantime, is there a cloud solution which could do this type of proxy append, so each home doesn't need to buy a hardware solution, that you're aware of, and is free like Open DNS? Thanks in advance.

    I'm not aware of a cloud solution.  The only solution I'm aware of is an own internal proxy server.  This can run on any old computer with a free proxy distro, zero cost, i.e. free as you expect.

    See https://support.opendns.com/entries/22262304-Google-image-block-instructions-in-conjunction-with-opendns-

    If you feel there's a significant market space for a cloud solution, why not start with such an enterprise?  Smells like lot of money...

    Thanks rb. I thought of that too. Unfortunately, working on the cure for death now, which takes up all my time. ;-)

    it would appear that the motor is not working, 0 checked articles from a large number of scratched with impressions areas. Will take a gander at the motor, perhaps I discover place to alter.

    I know this is an old thread, but thought I would mention that any home router that uses dnsmasq can redirect any url/website request to another ip.  In this situation I redirect all requests for search engines to google's safe search.  BTW, all openwrt, ddwrt, wrt, etc, enabled routers have the dnsmasq option.

    Dnsmasq settings
    Make sure to set the dns server that dhcp is handing out to the ip of the router.
    #Set this ip to the ip address of your router.  DNS requests will go through your router first and then to the DNS servers you set below (Open DNS).
    dhcp-option=6,192.168.2.2

    This is a copied from my dnsmasq settings for the gateway router the kids and guests use.

    #Set DNS Servers to OpenDNS
    server=202.67.222.222
    server=202.67.220.220
    server=202.67.222.220
    # Safe Search
    address=/www.google.com/216.239.38.120
    address=/www.bing.com/216.239.38.120
    address=/www.yahoo.com/216.239.38.120
    address=/www.youtube.com/216.239.38.120

    Sure, any authoritative DNS server software is able to do it.  This is what Google say: https://support.opendns.com/entries/57304954

    YES

     

    Despite OpenDNS denying its impossible, you CAN do it

    Just install Comodo DNS - they even block tor nodes, so FAR superior to open DNS

    You can also install DD-WRT and turn it on there

     

    Sorry guys.. you're losing by being ignorant.

     

    Good luck with twitter though, not worked that one out

    I'm just a user, but I cannot see that they are ignorant or denying anything.

    SafeSearch functionality is fully included and supported in their Umbrella product.
    https://docs.umbrella.com/deployment-umbrella/docs/what-is-safesearch

    And honestly, I do not see a motivation why they would give such features away in the free service.  Would you?
