How to use this tool
- Paste IP data (one entry per line) and choose whether CIDR is allowed.
- Run validation and inspect status, version, and classification columns.
- Export CSV/JSON outputs or copy normalized valid entries.
Validation depth
- Supports IPv4 and compressed IPv6 formats.
- CIDR suffix validation enforces 0-32 for IPv4 and 0-128 for IPv6.
- Bulk diagnostics explain why invalid rows fail.
Classification
- Flags private, loopback, link-local, multicast, and documentation ranges.
- Differentiates IPv4 and IPv6 totals for network planning workflows.
- Normalized output helps with downstream allow-list automation.
FAQ
- Can I validate CIDR networks?
- Yes, when the CIDR toggle is enabled. Prefix lengths are validated by IP version.
- Does this validate reachability or DNS mapping?
- No. It validates syntax and classifies address ranges only.
- Is this a server-side check?
- No. Validation and exports are fully client-side.
