Subnet / CIDR Calculator — Free, No Upload, Browser-Based
🔒 Funziona nel tuo browser
Enter any IP address and CIDR prefix length to instantly see the network address, broadcast address, usable host range, subnet mask, wildcard mask, and total host count — all calculated in your browser. No IP address or network data is ever transmitted to a server, making it safe for inspecting internal or sensitive network ranges.
Come usare questo strumento
- Digita un indirizzo IP e regola il cursore della lunghezza del prefisso o digita un blocco CIDR come 10.0.0.0/8.
- Il calcolatore mostra istantaneamente indirizzo di rete, broadcast, subnet mask, wildcard mask e intervallo di host.
- Copia qualsiasi singolo valore con il pulsante Copia accanto a ogni riga di risultati.
