192.168.0.0/24
Private (RFC 1918) RFC 1918The most commonly encountered home network subnet. Routers from brands like ASUS, Netgear, and TP-Link default to 192.168.0.1 as the gateway, serving the 192.168.0.0/24 range.
Network address — the base address of the block (192.168.0.0). All devices in this subnet share this prefix. Cannot be assigned to a host.
Broadcast address — packets sent to 192.168.0.255 are delivered to every device in the subnet. Also reserved — not assignable.
Usable hosts — the 254 addresses between those two that you can assign to servers, VMs, or interfaces.
Subnet mask — 255.255.255.0 is the dotted-decimal equivalent of /24. Older tools and Cisco configs use this format instead of CIDR slash notation.

Binary Representation
The first 24 bits (1s in the mask) identify the network. The remaining 8 bits identify hosts within the network.
Subnet Breakdown — splitting into /25
This /24 block can be divided into 2 /25 subnets.
| CIDR | Network | Broadcast | First Usable | Last Usable | Hosts |
|---|---|---|---|---|---|
| 192.168.0.0/25 | 192.168.0.0 | 192.168.0.127 | 192.168.0.1 | 192.168.0.126 | 126 |
