I am seeing a lot of posts that suggest that peer discovery isn't possible on private networks. Here is one:
Automatic peer discovery in a private blockchain
And another (less clear on this point):
Peer discovery not working on private network
So that raises a few questions:
1) Is that actually true?
2) Is it true with Parity as well as geth?
3) If (1) is true, then does anyone know how Expanse, etc. handle peer discovery?
Thank you.
