So I'm working from a local cafe, doing some web development, and need to see something in my Apache's access log. And to my surprise, in the log I see, every 30 seconds or so, a request for my root web page, coming from 192.168.1.1 -- the cafe's Verizon router.
Is this a normal or known behavior? Or is it Bad?
The web server is running on my laptop, which is physically in the cafe with me. The server is supposedly private -- there's no public website or public IP address. I just use it for testing and development. I can't think of any well-intentioned reason for someone, let alone some bot running on, or via, a wi-fi router, to be asking for /index.html every 30 seconds. Or is every public wi-fi hotspot router asking every end-user for access to port 80?
