194.0.0.0/7
PublicClass C — /7 prefix — 33,554,430 usable hosts
Network address — the base address of the block (194.0.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 195.255.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 33,554,430 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 254.0.0.0 is the dotted-decimal equivalent of /7. Older tools and Cisco configs use this format instead of CIDR slash notation.
