Hello Prof Lin, I'm sending you this link so you can look at it and see if you would like to forward it to the rest of the students in Web Systems. This allows students to create a hostname for their website. The only thing students will need to do on there own is to open the port on their router that their website is hosted on Xampp hosted port 80 on the computer(192.168.1.50:80) then the student will need to forward that port on their router to the computer. The website for free Hostnames: www.noip.com Have a great day! -Nick Bauer
