232.0.0.0/6
Multicast RFC 5771Class D (Multicast) — /6 prefix — 67,108,862 usable hosts
Network address — the base address of the block (232.0.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 235.255.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 67,108,862 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 252.0.0.0 is the dotted-decimal equivalent of /6. Older tools and Cisco configs use this format instead of CIDR slash notation.
