Interactively divide and join IPv4 subnets
RFC1918 Private Ranges: 10.0.0.0/8 (10.0.0.0 – 10.255.255.255) · 172.16.0.0/12 (172.16.0.0 – 172.31.255.255) · 192.168.0.0/16 (192.168.0.0 – 192.168.255.255)
Enter a valid IPv4 address
Between 0 and 32
Click "Divide" to split subnets into smaller networks. Click on the grey mask indicators to join subnets back together.
| Subnet Address | Address Range | Usable IPs | Hosts | Divide | Join |
