> Even ISPs that deploy IPv6 are doing it for business and financial reasons. The two first hand instances I have experience with are (a) for marketing reasons around 10 years ago, because the company liked to consider itself a technology leader and (b) to save IPv4 CGNAT costs.

(b) seems to be why ISPs will progressively prefer to push mobile, domestic and SOHO users towards IPv6 and to box IPv4AAS into as small a corner as possible. But what will be the cost that causes ISPs to do the same for large enterprises?
