Calculate exact subnet boundaries, masks and address counts for IPv4 and IPv6.
Choose your inputs and calculate to see the report. IPv6 address counts retain full precision.
Enter an IPv4 or IPv6 address with a CIDR prefix. Calculate to see normalized network boundaries and exact address counts. IPv4 /31 uses point-to-point conventions; /32 represents a host route. IPv6 has no broadcast address.
You can complete three tools as a guest across this collection. Continue with Google for further use. Failed operations do not consume a successful use.
Calculations run in your browser. Only tool usage and outcome are sent for account limits and analytics; entered network values are not sent.
Reports describe address ranges, representations or timing estimates from your inputs. They do not discover connected devices, configure your network or measure a live connection. Tool-specific assumptions appear beside the result.
Yes. You can complete three successful operations across this tools collection as a guest. Continue with Google for further use. Failed operations do not reduce the successful-use allowance.
Usage analytics record the tool, account or browser identity, status and time, without storing input text, passwords, tokens or file contents. Your content is processed in your browser.
