Domain to IP Converter

Resolve a hostname to its addresses.

How it works

Resolve any domain to its IPv4 and IPv6 addresses

Enter a hostname and get every A and AAAA record it currently publishes, with TTLs, any CNAME in the chain, and who owns the address block: reverse DNS, network name, organisation, country and ASN. That tells you in one screen whether a site sits behind Cloudflare, on AWS, Vercel, a Nigerian host or a server you forgot about. Lookups go straight to public DNS-over-HTTPS resolvers, so the answer is live, not cached by your ISP.

Results appear here after you click Resolve.

How this works

1
Query public resolvers
We ask Cloudflare's DNS-over-HTTPS resolver (Google as fallback) for A, AAAA and CNAME records.
2
Identify the owner
Each address is looked up in the regional internet registry to find the network, organisation, country and ASN.
3
Explain what it means
We flag proxies like Cloudflare, private addresses, missing IPv6 and records split across providers.

Frequently asked questions

How do I find the IP address of a domain?: Type the domain into this tool and read the A (IPv4) and AAAA (IPv6) records. On a computer you can also run nslookup example.com or dig example.com, but those use your ISP's resolver, which may still be caching an old answer.
Why does a domain have more than one IP address?: Larger sites publish several A records so traffic is spread across multiple servers, and CDNs such as Cloudflare answer from an anycast range. Any of the listed addresses will serve the site; browsers pick one and fail over if it is unreachable.
Why is the IP address not my hosting server's IP?: If the site is behind Cloudflare or another proxy/CDN, DNS points at the proxy's edge network and the origin server stays hidden. The network owner shown in the result tells you which proxy is in front.
What is the difference between an A record and a CNAME?: An A record maps a name directly to an IPv4 address (AAAA for IPv6). A CNAME says 'this name is an alias of that name', so the address is whatever the target publishes. Platforms like Shopify, Vercel and Netlify usually ask for a CNAME so they can change IPs without you updating DNS.
Can I find out who owns a domain from its IP address?: Not the person: the IP registry tells you which hosting company or network owns the address block, not who rents the domain. For registrant details use a WHOIS/RDAP lookup on the domain itself, bearing in mind most registrants are redacted for privacy.

Every MailShrine domain includes WHOIS privacy, transfer lock, Anycast DNS with DNSSEC and two business mailboxes.
