231.9.131.192/26
Multicast RFC 5771Class D (Multicast) — /26 prefix — 62 usable hosts
Network address — the base address of the block (231.9.131.192). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 231.9.131.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 62 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.192 is the dotted-decimal equivalent of /26. Older tools and Cisco configs use this format instead of CIDR slash notation.
