   - `listen` addresses will be provided to the libp2p underlying transports for listening on them.
   - `announce` addresses will be used to compute the advertises that the node should advertise to the network.
   - `noAnnounce` addresses will be used as a filter to compute the advertises that the node should advertise to the network.
+  - `announceFilter`: filter function used to filter announced addresses programmatically: `(ma: Array<multiaddr>) => Array<multiaddr>`. Default: filter all private addresses.
