How to choose DNS:

In China, generally using the several domestic DNS servers I provided is fine. If you are overseas, it is recommended to choose overseas public DNS servers. Additionally, after testing, 114DNS, Baidu DNS, and Tencent DNS can be used in most overseas regions, while AliDNS has poor connectivity in many overseas regions.

What are DoT and DoH:

Both DoT and DoH are methods of encrypting DNS. The difference lies in the protocols and ports they use. Both are types of domain name resolution security extension protocols.

Concepts:

DoT stands for DNS over TLS, which uses TLS to transmit the DNS protocol. DoH stands for DNS over HTTPS, which uses HTTPS to transmit the DNS protocol. The principles of both protocols are the same. They encrypt the DNS messages between the user and the DNS server to prevent eavesdropping by intermediate users and leakage of domain name query privacy. Relatively speaking, DoH is more versatile.
