SSH Connections

How many parallel SSH connections can be opened in a single instance of Confd at a time.
For example if there are 1000 IP’s created on a Linux Machine. Is it possible to make a single instance of Confd listen to all 1000 IP’s over ssh.
I guess the above is possible if we give 0.0.0.0 is ssh IP. But in this case, how many parallel connections can be served by Confd. For one of our application, there can be a chance where all 1000 IP’s needs to eb connected over SSH at a time. Is this possible in Confd. Is there any solution for it.
