Nope, in my "first world" country, some consumer IAPs does offer a static IPv4 with a non-filtered SMTP port and a static IPv6 prefix (usually a /64 which is very convenient to change email address/hosting IPs when compromised, well if you use an address email with an IPv6 literal). But I don't really use IPv4 anymore for my self-hosting, IPv6 has been around _here_ for a very, very long time for nearly everybody if not everybody (even mobile internet).

Yes, I know my IPv4 is the target of distributed port scans, by IPs known as compromised by the "security" community. I guess my IAP "security" team knows, and they may probably be 'in the process of doing something to deal with them'... (which would more than IP blocking and would involve authorities...).

FTTH(8GB), static IPv6, static IPv4 plus opened SMTP port, ~30 bucks a month (for millions).
