Questions about this tool
Why does my domain show two or more IPs?
Big sites and CDNs use many servers for speed and safety. Each IP is valid.
Why is there no IPv6?
The site has no AAAA record. It still works for everyone through IPv4.
Can I find who hosts a site?
Use our Domain hosting checker. An IP alone does not always show the hosting company.
Is my list sent to your server?
No. Your browser asks a public DNS service directly.
Why is there a limit of 50?
To keep it fast and polite to the free DNS services.
