It's actually been a little while since I messed with ngrok, I believe to set the actual hostname, you must used the paid version of ngrok.

I'm not sure I understand your request then.
ngrok creates an external URL and then tunnels it to your internal application. What do you mean by I want a random IP. You want the external URL to have a random IP? A random hostname?
I'm not sure what you're trying to accomplish, because if you want to "name" the URL that someone connects to, then you have to pay for that. Either that, or use your own domain and create a CNAME to their provided URL / hostname.
Bro, see my previous answers. If you want to change it. Pay ngrok. Otherwise, deal with the free tier's limitations or buy a domain and CNAME it.bro its not creates external random url, etc randomurl.ngrok.io it creates like that random-my-ip-here.ngrok.io i dont want show someone my ip
its free for random url,i have watched on yutube how free plan works ,its creates random link ,my ngrok creates random links included my ip address in urlBro, see my previous answers. If you want to change it. Pay ngrok. Otherwise, deal with the free tier's limitations or buy a domain and CNAME it.
