FAQ

Can CIDR ranges be expanded directly to complete IP lists?

Yes. Enter CIDR range or start-end IP to get complete address list directly, especially suitable for inspection, scanning, and configuration verification.

Besides CIDR, does it support start IP to end IP ranges?

Yes. Whether standard network ranges or custom start-end ranges, all can be quickly expanded, convenient for handling irregular address intervals.

Is it suitable for whitelists, inspection, and batch tasks?

Yes. Many ops scenarios require first listing range addresses, then importing into scripts, scanners, or firewall policies.

Can the expanded IP list be copied directly?

Yes. Results are suitable for one-click copy then continued use in script execution, ticket records, or config file maintenance.
