Scripting newbie - cycle through IP addresses?

Projects Networking, Protocols, and Devices
1

I have a class of students using Unos and Ethernet shields running server software. Is there a way I could run a script of some kind to call on each of 12 different Ip addresses, one by one, for 5-10 seconds, to check the web page for each? I'd like to just cycle through all 12 to keep track of data each student is posting on their web site.
Thanks!

If you mean that you want to use the Arduino as client to access several different IP addresses, that is possible.

I don't really see this as an Arduino task. Bookmark the 12 sites on your PC, and look at all 12 at once.

That's quite easy:

for ip in "10.20.30.1" "10.21.31.2" "10.22.32.3" "10.23.33.4" "10.24.34.5"
do
  curl "http://$ip/path/to/project.html"
done

Runs on almost every Linux machine (curl must be installed), also a Raspberry Pi.
Is it that what you're looking for?

Paul S & Python - thanks ... the reason I wanted to do it on the Arduino was to transition into using server tasks on the Arduino and that seemed like a neat sketch for them. Python the curl looks like the
easiest approach TNX will try it

I think it's far more important to teach using the right tool for the job. But, maybe that's just me.
