141.98.184.0/21
PublicClass B — /21 prefix — 2,046 usable hosts
Network address — the base address of the block (141.98.184.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 141.98.191.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 2,046 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.248.0 is the dotted-decimal equivalent of /21. Older tools and Cisco configs use this format instead of CIDR slash notation.
