ADVERT
IP Address Validator
Validate IPv4 and IPv6 addresses in bulk with CIDR checks, classification, and exportable reports.
How to use this tool
- Paste IP entries (one per line) and optionally enable CIDR parsing.
- Run validation to review status, version, and range classification.
- Copy normalized valid entries or export CSV/JSON results.
Validation depth
- Supports IPv4 plus compressed and mixed IPv6 forms.
- CIDR ranges are validated by IP version limits.
- Bulk diagnostics explain invalid lines for faster cleanup.
Classification output
- Identifies private, loopback, link-local, multicast, and documentation ranges.
- Separates IPv4 and IPv6 totals for quick traffic-list audits.
- Normalized output helps downstream allow-list automation.
FAQ
- Can I validate CIDR networks?
- Yes. Enable CIDR mode and prefix lengths are checked per IP version.
- Does this test reachability or DNS?
- No. It validates syntax and classification only.
- Is validation performed server-side?
- No. Checks and exports run locally in your browser.
