На DNS‑сервере(ах) вы настроите запись («`A record`» - запись типа A), указывающую, что **ваш домен** должен указывать на публичный **IP‑адрес вашего сервера**.

Обычно это делается один раз — при первоначальной настройке всего.

Часть про доменное имя относится к этапам задолго до HTTPS, но так как всё зависит от домена и IP‑адреса, здесь стоит это упомянуть.
