I found out that someone who used to have my current IP address, still has an old A record and google is using that for returning search results. As a result, when someone searches the name of my website in google, it shows their url and my sites metadata and name. And when anyone clicks on the link it goes to our website but uses their domain name. (Displays invalid security certificate though)
I have already done a whois lookup and made an attempt to connect the owner of the registered domain name.
If i never hear back, what can I do to fix google search results?
