Can a SSHD access a dynamic DNS host?
You can login normally as you do for any other server. Using the DNS or IP of the server doesn’t matter. It’s the sshd that’s resolving your dynamic dns host and allowing you access. It’s a good security measure but personally I don’t use it as there is a third party involved in the login process.

Why is SSH not able to connect to DNS?
Fundamentally, DNS does not have that ability. The client resolves a DNS name into an IP, then attempts to connect to that, so this information is lost at connect time (unless SSH transmits it in a way the server can use it pre-login, which I don’t think it does). Cribbed from another SF question, how ’bout this?
How to restrict SSH to a specific hostname?
Only user names are valid; a numerical user ID is not recognized. By default, login is allowed for all users. If the pattern takes the form USER@HOST then USER and HOST are separately checked, restricting logins to particular users from particular hosts.
Why do we have website virtual hosts in SSH?
Once the client gets an IP, it can ONLY make a TCP/IP connection. The server only sees IPs, so it has no idea what name the client used to find the server. The reason we have website Virtual hosts is because the client transmits a header asking for a specific host.
