How does Open DNS work? Essentially, it replaces the DNS lookups that the Internet Service Provider (ISP) gives us so that when we request a Website, OpenDNS can decide if it we want it blocked or not. To do this we point our router and the lookup servers provided by OpenDNS and not to the servers provided by our ISP.
I recently changed my router provided by my Internet Service Provider (ISP) and for some reason imagined that OpenDNS was still configured. Of course it wasn't. I checked the control panel of the router and found I was using the ISP's DNS servers and found no way to change them. So the solution is to use Telnet.
First, check you are using OpenDNS.

You should see a big tick if you are already configured.
If you see the tick - all is good. Ignore this blog post.
I needed the Username and password for the router,
and the OpenDNS ip addresses. These are they:
- 208.67.222.222
- 208.67.220.220
On a Mac you simply open Terminal, (CMD-Space then type terminal is one way to open it.).
Not sure what Telnet client you'd use on Windows.
I am assuming the IP address of the router is 192.168.1.254, if not, use the correct one instead.
type: Telnet 192.168.1.254
JMBP:~ jr$ Telnet 192.168.1.254
Enter the Administrator's user name and password and you should see something like this:

Command prompt,
You will see the following prompt, type commands after the prompt.
{Administrator}=>
Look at the list of DNS servers you currently have. Mine are for ZEN.
Typing, dns server route list
{Administrator}=>dns server route list
will list your current server list.
{Administrator}=>dns server route list
DNS Server Entries:
DNS Server Source Label Metric Intf State Domain
D 212.23.6.100 10 Internet UP *
D 212.23.3.100 10 Internet UP *
Flush the list, thus:
{Administrator}=>dns server route flush
Now add the two Open DNS server addresses:
{Administrator}=>dns server route add dns=208.67.222.222 metric=10 intf=Internet
{Administrator}=>dns server route add dns=208.67.220.220 metric=10 intf=Internet
Now list them to see if they are there:
{Administrator}=>:dns server route list
And we see:
DNS Server Entries:
DNS Server Source Label Metric Intf State Domain
S 208.67.222.222 10 Internet UP *
S 208.67.220.220 10 Internet UP *
Now Save and exit:
{Administrator}=>saveall
{Administrator}=>exit
Worked for me. Good luck.
