As I said, really not that many, to a point I was about to turn off IPv4. Ofc, it depends on your usage. But what's very surprising are those Big Tech sites, with billions of $ and still IPv4 only, like msft github (and github has still its core functions working with noscript/basic (x)html browsers). What is really bothering me is the admin of the mail server of my medical insurance company: IPv4... but that's not what is the most annoying, the most annoying: it is not white listing its client SMTP servers/client emails... this is another level of bad.
