During cluster expansion, Nutanix uses the Controller VM discovery service, which relies on multicast-based node advertisement. The internal architecture documentation states:
“Node discovery during cluster expansion requires IPv4 multicast to be enabled and permitted on the switching infrastructure.”
This allows new nodes to announce themselves to the existing cluster through standard Nutanix discovery packets.
IPv6 multicast is not used for node discovery. Matching AOS or hypervisor versions is recommended for compatibility but not required for discovery itself. These are post-discovery compatibility concerns, not prerequisites.
Thus, IPv4 multicast is required for automatic node discovery.
