This used to be true until virtual hosting came along, allowing for several domains to point to the same IP address, but only for non-HTTPS traffic. Then a bit later we got SNI (Server Name Indication) that did the same thing for HTTPS.
I remember having web servers with 10-12 public IP adresses when I started working. The number of IPv4 addresses needed has been greatly reduced since.

The fact that a server can serve multiple vhosts and do TLS cert selection via SNI is not related to the lookup of what server to connect to.
