89.64.0.0/10
PublicClass A — /10 prefix — 4,194,302 usable hosts
Network address — the base address of the block (89.64.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 89.127.255.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 4,194,302 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.192.0.0 is the dotted-decimal equivalent of /10. Older tools and Cisco configs use this format instead of CIDR slash notation.
