I am a newbie here

When I first installed the bitnami wordpress to my cloud hosting it can accessed by public IP address. After that I have added a domain name successfully, everything went well.. But still my website can be accessed by IP address. And I don't want that because Google has indexed my IP address too. It's looks like this in search engine https://13.233.54.98/my-post.

And also I have been getting duplicate warning from jetpack, it says that this "trendinhub.fun" ( my website) is exact copy of "trendinhub.fun" , turning on safe mode. Is it beacuse of IP address? I don't know

So how can I disable my public IP address permanently. Thanks in advance.
