We should also have an affirmative test that shows the ip blocking works. |

I've moved the logic to the tcp_listener::on_connection function. I will try to add some unit tests next |

There was a problem hiding this comment.
I think this should remain a debug log as it could be high-volume.

This PR introduces an optional list of ip addresses that a node operator wants to ignore. The peers are inserted in the config file as "blocked_peers"
Both ip v4 and v6 address formats are supported and can be mixed. Example:
blocked_peers = ["::ffff:10.0.0.1", "192.168.0.1"]
This could be useful for blocking malicious nodes.
