dnscrypt proxy stamp changes for ultralow
The dnscrypt proxy stamp on the suggested setup page hardcodes the ip address of dns.nextdns.io to an anycast server. By removing the ip address from the stamp, the system resolver will resolve the hostname to a CDN resolved ultra low server instead. I think this is overall better. Optionally, add a line to have the original ip address as a fallback server e.g:
fallback_resolvers = [ '220.127.116.11:53','18.104.22.168:53']
To do this manually, you can edit the stamp here: https://dnscrypt.info/stamps/
I suggested dnscrypt-resolvers add an ultralow public server (no IP address attached) here https://github.com/DNSCrypt/dnscrypt-resolvers/issues/638
And then I suggest changing the config file to use DNS servers with ECS that help resolve the nextdns-ultralow servers in the countries the users use https://github.com/DNSCrypt/dnscrypt-proxy/pull/2056
So I think dev nextdns just need to remove the IP built in stamp and use it without changing the bootstrap resolver.
