Add OpenNIC DNS Servers

I'd love to see OpenNIC servers added to the default list, it's been around since 2000 and it's relatively popular among privacy-minded techies :wink:

There's a lot of DNS servers available since it's a community project, but I think it'd make the most sense to add the main Anycast servers:

  • 185.121.177.177 2a05:dfc7:5::53
  • 169.239.202.202 2a05:dfc7:5353::53

Edit: see my post below.
