This is normal, because multiple resolution records can be added during domain name resolution, including omitting the default @ of www, and then there are other record types, such as www, blog, email of Class A, you can change it as you like, as long as The IP addresses they resolve are the same, and no matter which domain name they use, they all access the same content

域名更加简短、容易记忆还有多域名SSL证书只支持不带www。

所以根据需求,单域名的话推带www,多域名的话只能不带www
