I built this tool to give developers a fast, privacy‑first way to resolve domains to both IPv4 and IPv6 without any third‑party APIs. It handles single queries or bulk lists, retries transient failures, and blocks private ranges. Please try a single domain lookup and let me know if anything breaks.

Free tool that resolves IPv4 and IPv6 addresses and DNS records for any domain, with bulk and export options.
- for
- Developers, infrastructure teams, security researchers, and privacy-focused users.
- pricing
- free
Key features
- Dual-stack resolution — Returns both A (IPv4) and AAAA (IPv6) records for each domain.
- Bulk lookups at scale — Paste thousands of domains; controlled concurrency keeps batches fast.
- CSV & JSON export — Download full results streamed as CSV or JSON without waiting.
- SSRF-hardened — Filters results against private, loopback and cloud-metadata ranges.
- Automatic retry — Transient DNS failures are retried with exponential backoff.
- No third-party API — Resolves directly using Node.js dns.Resolver against public DNS servers.
Use cases
- Verify that a DNS change has propagated after updating a record.
- Check mail server configuration and SPF/DKIM/DMARC settings.
- Monitor a portfolio of domains for unexpected IP changes.
- Safely resolve large domain lists for security research.
- Replace dig/nslookup for quick one-off lookups.

Domain IP Lookup FAQ
Does this use a third-party IP lookup API?+
No, it resolves directly using the server's own DNS resolver.
Is there a limit on bulk lookups?+
Per-visitor rate limits and bulk job caps are applied to keep the service fast for everyone.
Can I look up internal or private IP addresses?+
Resolved addresses are filtered against private and loopback ranges before being returned.
What happens with a domain that doesn't resolve?+
Permanent failures like NXDOMAIN are reported immediately; transient errors are retried.
Can I export my results?+
Yes, results can be downloaded as CSV or JSON files.
Why does a domain resolve to more than one IP address?+
Multiple IPs are common for load balancing, CDNs, or redundancy.
