The public DNS server here refers to the DNS domain name resolution server used locally by our computer. Generally, when we connect to the broadband, we will automatically obtain the DNS server of the local ISP.

Also, when visiting shopping websites such as Taobao and JD.com, you clearly enter the official website URL, but after opening it, you always find that the URL has a "little tail".
