ISP says there's no demand for IPv6 addresses. There's no demand because other people don't have them. Others don't have them because ISPs don't issue them.

ISP says there's no demand for IPv6 addresses. There's no demand because other people don't have them. Others don't have them because ISPs don't issue them. It's not circular logic, it's no loose ends. Reminds me of a story in The Dragon Book. (compiler design book from the 1970s) FORTRAN IV doesn't (didn't) allow arrays with more than three dimensions. Because programmers didn't write programs using arrays with more than three dimensions. Programmers didn't write programs using arrays with more than three dimensions because the compiler didn't allow arrays with more than three dimensions.
