When you do holesail CONNECTOR, it generates a hash that is also your location in the distributed hash table, atm there are two public nodes run by hopepunch team which lets you in on the mesh network of peers.

Anyone can run a public nodes, and it's only used for initially finding first few peers after that other peers tell you where your "peer" is located.

To stop people from taking over, you need to use key, which are automatically generated.

holesail --live 5000

will give you a key
