In testing DOH(DNS over https), encrypted SNI(Server Name Indication) was not enable for brave browser. To reproduce, I’ll be using cloudflare dns. Install config file from here - https://paulmillr.com/posts/encrypted-dns/ in safari iOS browser because config profile install doesn’t work in brave iOS. Then check dns over https here - https://www.cloudflare.com/ssl/encrypted-sni/ in brave iOS browser.
The benefits to enabling will be the hostname will be private in a tls connection.
