Is there a 'A' record in DNS for server A as well as a reverse lookup

What happens if you try to ssh by IP address or put the IP address in
your /etc/hosts file on B?

Is there a software firewall on A that does not allow ssh connections?
I'm assuming of course that you already have an ssh server up and
running on A.

P.S. Sorry for the top posting.
