How do I do a reverse DNS lookup from IP address to domain name?

I want to know the source of a server IP address domain name. For example, as shown in the picture, the domain name meping.igamecj.com replies with 20 addresses, so my main question is how do I use any of these 20 addresses to trace back to that Domain name?
