104.198.96.0/20
PublicClass A — /20 prefix — 4,094 usable hosts
Network address — the base address of the block (104.198.96.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 104.198.111.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 4,094 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.240.0 is the dotted-decimal equivalent of /20. Older tools and Cisco configs use this format instead of CIDR slash notation.
