唔清楚,能力所限同埋冇ipv6 equippment,要等高手答
可能呢個114 setting係只限ipv4 environment先有,又或者114根本冇ipv6
不過而家嘅情況我覺得除咗被default DNS3 114之外,仲有系統app唔跟Android P指引,app內hardcode 114DNS之餘,仲要喺有Private DNS嘅情況下擅自唔用DNS-over-TLS做密文DNS queries而走去用114做明文DNS queries (暫時發現到有www.qq.com同news.qq.com.edgekey.net,另外hao123.com嘅明文queries喺有Private DNS之後就冇晒了)
