88.104.0.0/15
PublicClass A — /15 prefix — 131,070 usable hosts
Network address — the base address of the block (88.104.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 88.105.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 131,070 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.254.0.0 is the dotted-decimal equivalent of /15. Older tools and Cisco configs use this format instead of CIDR slash notation.
