    Did you use IPv4 or Ipv6 settings or both?

    Regardless of what jnjewlz did...

    If you have a dual-stack (IPv4 & IPv6) connection, then you configure DNSv6 from the following list of addresses:
    ::ffff:d043:dedc   ::ffff:d043:dcde   ::ffff:d043:dede   ::ffff:d043:dcdc

    If you have an IPv6-only connection, then you use the following DNSv6 resolver addresses:
    2620:119:35::35   2620:119:53::53
    Please note that your dashboard settings and stats are not being used then, but the default OpenDNS settings which is blocking phishing and some malware domains.

    If you have an IPv4-only or dual-stack connection, then you clearly use the usual DNSv4 resolver addresses to configure the IPv4 side.

    Thank you for your comment.


    I have a IPv4 connection: 



    Heres what I am doing but still having trouble. 
    Control Panel\All Control Panel Items\Network Connections -> Properties ->IPv4 -> Properties -> Use Following DNS Server addresses: Preferred DNS Server:, Alternate DNS Server: Okay, Close.
    But it doesn't stick. 
    I also did this from my Unifi Controller, it shows up correctly when I go back in but I still show to be inactive on the Umbrella Dashboard.

    I'm confused.  This thread is about configuring OpenDNS on the Ubiquity UniFi Security Gateway, and you seem to refer to settings on a Windows computer now...

    Also, this forum is for OpenDNS (home) users, not for Umbrella users.  If you're an Umbrella user/customer, please open a support ticket at https://support.umbrella.com/hc/en-us/requests/new

    If you're an OpenDNS (home) user, then copy & paste the complete plain text output of the following diagnostic commands to here, so that I may see what your problem is:

    nslookup -type=txt debug.opendns.com.
    nslookup whoami.akamai.net.
    netsh interface ipv4 show config
