If you use a router (More than one computer in the household network on the same ISP account), the router assigns the IP number you see when you do an “ipconfig” on your computer You have to log in to the router itself if you want to see the IP address the ISP provides. Mine changes weekly.
Thank you for the quick lesson for computer illiterates. :-)
You can get a new IPAdress pretty easy by signing up for a free dailup provider, there are bunches of them and FR is doable with dialup. I use dialup as a backup for when my DSL goes out. Not pleasant but useable.
