But when I navigate there Chrome says This site can’t be reached . 回答1: Just use host command and specify your public IP - it will show you the right URL, e.g. $ host 52.204.122.132 132.122.204.52.in-addr.arpa domain name pointer ec2-52-204-122-132.compute-1.amazonaws.com. where ec2-52-204-122-132.compute-1.amazonaws.com is your domain. So you

问题 I have created some web app using Rook which listen to my network ip (192.168.xx.xx) at port 8000.

I need to monitor these pages usage and wonder how I can get the network ip address of those connected to them. I'm not experienced in web development and from the research done so far it seems that using client side code like JavaScript it's very difficult (almost impossible) to achieve
