You could just bruteforce IPv4 until you hit a peer that will give you a set of known peers.

I don't think pex/dht operate on 'well known' ports. in fact, I think most clients are configured to randomize the port they use on each startup.

most every client comes with a list of 'bootstrap peers' for dht though.
