A redirect message plays a crucial role in network routing by suggesting an alternative gateway to the source of the data packets. When a router receives a packet that has a destination address not directly accessible, it can determine that there is a more efficient route available. By sending a redirect message back to the source, the router informs it of a different next-hop gateway that would allow for improved routing efficiency and reduced latency. This process enhances network performance by enabling the source to adjust its routing table and make better decisions on packet forwarding in the future.

The other roles mentioned in the options do not align with the function of a redirect message. While dropping packets pertains to routers' actions under certain circumstances, confirming packet receipt is more relevant to acknowledgments in transport layer protocols, and increasing the speed of packet transmission is not a characteristic of redirect messages but rather of network design and optimization techniques. Therefore, the primary function of a redirect message is to improve routing by informing the sender about a more optimal path, confirming the accuracy of the correct response.
