How is the list of preset DNS servers in WAN settings generated?

[wndsrc]

Hi
This isn’t a technical support question like which one to use etc or an ideological one like why isn’t foo or bar server included.

When I look at the available list of preset DNS servers in the WAN settings I get this list in the screenshot (AdGuard, Control-D, Cleanbrowsing).

When I look at the source code eg https://github.com/RMerl/asuswrt-merlin.ng/blob/main/release/src/router/www/ajax/DNS_List.json there are other servers listed there, same as in the dns director file and other files.

How is the list in the webui generated? I couldn’t find any history in the changelog of options being removed like OpenDNS or Cloudflare, but while they are the the source they aren’t shown in the webui list.

Hopefully this makes sense.

Only the entries where “confirmed” equals “Yes” are displayed.
