Instances attached to one Vultr VPC share multicast traffic, so a single stream reaches many instances.
Yes, Vultr VPC supports multicast, a network communication method that enables one-to-many or many-to-many transmission of data to multiple recipients efficiently. It is commonly used for streaming media, real-time data distribution, and large-scale service discovery.
A single Vultr VPC can be attached to multiple instances, allowing all connected instances to participate in multicast traffic. This enables a single data stream to reach multiple instances at once, reducing bandwidth usage compared to sending separate unicast streams. Multicast operates entirely within the VPC, providing efficient intra-network communication while maintaining isolation from other networks or the public internet.
