Thanks for your considerations.
DNS validation usually only complicating things. TTL and stuff like that.
Usually, when i need to use other than 80 or 443 port, it means i have unable to use native ports in any of suggested scenarios. There are a lot of cases even in this thread, and many other threads.(here for ex.)
They can be provider-blocked, i may have a need to use nat to forward a port to specific host, there are tons of usage scenarios, and based on number of questions around the net, it’s a needed feature.
Why the hell it haven’t been implemented yet?
