These can be specified from both the nodeos command-line or the config.ini file:

Config Options for eosio::net_plugin:

                                        The actual host:port used to listen for
                                        incoming p2p connections.
  --p2p-server-address arg              An externally accessible host:port for

                                        connect to. Use multiple
                                        p2p-peer-address options as needed to
                                        compose a network.

                                          The optional 'trx' and 'blk'
                                        indicates to node that only
                                        transactions 'trx' or blocks 'blk'

                                        once. If only 'producers', peer-key is
