Why are my domain names resolved for a few days and I still use the original IP address when I ping my computer?

Why is my domain name resolved for a few days? Can I ping my computer or the original IP address? my domain name was originally bound to 192.168.1.3 for local debugging and then bound to the IP address 222.186.50.211, after this takes effect, all other computers have directed to this IP address, and all Lan, friends, and customers have directed to 222.186.50.211.

However, my computer is still pointing to the IP address 192.168.1.3. I have restarted my computer several times, changed the IP address, and cleared the dns cache, I have repaired my computer, and I have done everything. I still keep pointing to 192.168.1.3.

Try to ping this domain name without www. but it can point to it normally. Why ??

Have you read the local hosts file?

Www is a subdomain name. you need to understand this concept.
If www.xxx.com and abc.xxx.com are of the same nature, they must be added to DNS. if they are not added, they will not be resolved.

Thank you! it's a local hosts file problem. just remove 192.168.1.3 www.moonyes.cn.
