Questions fréquentes
- Quels formats d'entrée sont pris en charge ?
- IPv4 addresses (e.g. 192.168.1.1), IPv6 addresses (e.g. 2001:db8::1), and CIDR notation (e.g. 10.0.0.0/24) are all supported.
- What subnet information is calculated?
- For CIDR input, the tool computes network address, broadcast address, subnet mask, first/last host, and usable host count.
- Does this tool send my IP to a server?
- No. All parsing and calculation is done entirely in your browser. No data leaves your device.
