    Post the complete plain text output of the following command:

    nslookup -type=txt which.opendns.com.

    Also post a link to an online manual of your Motorola SURFboard.

    Although you can use OpenDNS, i.e. your ISP is not redirecting your DNS queries, you do not seem to be able to enter static DNS resolver addresses on this device.  This means you had to configure the resolver addresses on the end user devices, or you had to hook another router or server in between where you can configure OpenDNS.

    As I have seen, the Motorola device also supports some kind of parental controls which you may want to use in addition to OpenDNS.

    I also have a motorola surfboard sb6141 and there doesn't seem to be a place to set the primary and secondary dns server. At least, mine does not have this ability. Is it possible my internet provider - comcast- changed the settings to disable?

    If this device was supplied by your ISP, then yes, they have certainly trimmed down its firmware to prevent you from doing such changes.  You may try with the OEM firmware for this device if this firmware supports entering static DNS resolver addresses.

    To add to what rotblitz said, if you are leasing the modem from Comcast you may not be able to do anything with the firmware.  In that case you normally need to use another router behind your modem or configure your computers directly.
