IP Lookup
Resolve a domain to its IPv4 and IPv6 addresses.
Frequently Asked Questions
Is the IP Lookup really free?
Yes — unlimited use, no signup, no credit card. We built these tools to help you audit sites without paying for a data subscription.
Does this tool store or share the URLs I check?
No. Each check runs live and we don't save your input. We keep a short-lived rate-limit counter (by IP) purely to prevent abuse; it is not linked to your results.
How accurate are the results?
This tool reads live, public data directly from the page or domain you enter — it does not rely on a paid third-party database, so it reflects exactly what is publicly visible right now.
This tool resolves a domain name to the IP address(es) its web server uses — both IPv4 and, where configured, IPv6. It's a simple but frequently useful check for verifying where a site is hosted, confirming a DNS change took effect, or gathering basic infrastructure information about a domain.
How to Use This Tool
Enter a domain and click Look Up IP. The tool resolves the domain to its current IP addresses.
What This Tool Checks
The IPv4 address (A record) and IPv6 address (AAAA record, if the domain has one) that the domain currently resolves to.
Understanding Your Results
The IP address is where the domain's server lives. Many sites sit behind a CDN or proxy like Cloudflare, in which case the IP you see belongs to the CDN, not the origin server — this is normal and often intentional for security and performance.
How to Fix Common Problems
If you changed hosting and the IP still shows the old address, the DNS change hasn't propagated yet or a cached record is being served — wait and re-check. If you get no result, the domain may not have a valid A record configured.
SEO Best Practices
Use this alongside the DNS Lookup tool for a fuller picture of a domain's hosting setup. If you run a site behind a CDN, confirming the public IP resolves to the CDN (not your origin) verifies your origin IP isn't accidentally exposed.
Example
Looking up a domain returns a Cloudflare IP range address rather than the hosting provider's IP — confirming the site is proxied through Cloudflare.
Common Mistakes to Avoid
Don't assume the IP you see is the actual origin server if the site uses a CDN — it usually isn't. Don't treat a shared IP (many sites on one address) as inherently bad; shared hosting is extremely common and not an SEO problem by itself.
