229.184.64.0/18
Multicast RFC 5771Class D (Multicast) — /18 prefix — 16,382 usable hosts
Network address — the base address of the block (229.184.64.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 229.184.127.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 16,382 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.192.0 is the dotted-decimal equivalent of /18. Older tools and Cisco configs use this format instead of CIDR slash notation.
