Hey, thanks for the article, awesome. Where does the IP 10.5.24.245 come from? And why does it require a second dns entry with \*.app.example.com?

Hey [mab](https://hashnode.com/@celcin), oh I see that seems a bit confusing. I have updated the post to explain it a bit more. The IP is the LoadBalancer IP and its not needed to create a second DNS entry, but I have explained it in the post. Let me know if anything is unclear. :)
