..But if you don't know what IP a peer is at, it's impossible to ask them, too.
Yes, it is necessary to know the IP and port of at least one peer in order to bootstrap yourself onto the network. That information has to come from outside the network. This is normally done using a combination of static files and DNS resolution. Once you're on the network, the IPs and ports of the rest of the hosts become available to you.
