Domain to IP converter
Turn any domain into its live IPv4 and IPv6 addresses. See CNAME aliases, the TTL of every answer and which network owns each IP, from Google or Cloudflare DNS and the regional internet registries.

IP addresses
Enter a domain above to see every IPv4 and IPv6 address it points to, with TTLs, CNAME aliases and the network that owns each IP.
Fair-use limit: 30 lookups per hour and 200 per day for each visitor IP address.
How a domain becomes an IP address
Browsers cannot connect to a name. DNS turns the name into addresses first, and knowing who answers explains most surprising results.
A and AAAA records hold the addresses
The domain's DNS host publishes A records for IPv4 and AAAA records for IPv6. A name can have several of each, and visitors' devices pick one.
A CNAME passes the question on
www.example.com is often an alias of a hosting or CDN name. The resolver follows the alias and returns the addresses of the final name.
Resolvers cache the answer
Google, Cloudflare and internet providers remember each answer for its TTL in seconds. Until it runs out, they keep handing out the same address.
Registries know who holds the IP
Every public IP range is registered with ARIN, RIPE NCC, APNIC, LACNIC or AFRINIC. Their RDAP service names the network, which is usually the host or CDN.
IPv4 and IPv6 compared
The two kinds of address this tool returns, side by side.
| Aspect | IPv4 | IPv6 | Good to know |
|---|---|---|---|
| DNS record | A |
AAAA |
This tool asks for both, in parallel. |
| Example | 203.0.113.10 |
2001:db8::10 |
IPv6 shortens runs of zero groups with ::. |
| Format | 4 numbers from 0 to 255, separated by dots | 8 groups of hex digits, separated by colons | Both identify one network interface. |
| Size | 32 bits, about 4.3 billion addresses | 128 bits, about 3.4 × 10³⁸ addresses | New IPv4 space has run out at the registries, so IPv4 is now traded or shared. |
| Private ranges | 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 | fc00::/7 (unique local) | Only work inside a local network. The tool labels them if a public name points there. |
| Speed and security | Depends on the network | Depends on the network | Neither version is automatically faster or safer. |
How this tool works
What happens between pressing Find IP and seeing the addresses.
You enter a domain
A domain such as example.com or a host such as www.example.com. Pasted links are trimmed to the host name.
The resolvers are asked
Our server asks Google Public DNS, Cloudflare DNS or both for the A and AAAA records, in parallel, over encrypted DNS-over-HTTPS.
Aliases and owners are found
CNAME aliases in the answer are shown in order. For up to 8 public addresses, the regional internet registry is asked over RDAP who holds the IP range.
You get the addresses
Every IPv4 and IPv6 address with its TTL and network owner, plus checks, ready to copy or download as CSV.
What this tool does, and what it doesn't
A plain list, so you know exactly what to expect.
This tool does
- Show every IPv4 and IPv6 address with its TTL
- Show CNAME aliases in the order they are followed
- Name the network that holds each public IP
- Label private, local and test addresses
- Compare Google and Cloudflare answers
- Copy the IPs or download them as CSV
This tool does not
- Reveal a server hidden behind a CDN
- Show the physical location of an IP
- Find the domain of an IP (use DNS lookup)
- Show MX, TXT or other record types
- Resolve private or internal names
- Store the domains you convert
Where your data goes
The name you enter is sent from our server to Google Public DNS, Cloudflare DNS or both, over encrypted DNS-over-HTTPS. The public IP addresses they return, without the domain name, are sent to the regional internet registry that holds them (ARIN, RIPE NCC, APNIC, LACNIC or AFRINIC) to look up the owner. They see our server, not you, and the target website is not contacted. Like any website, our server may keep normal access logs, as described in our privacy policy.

Why your results might look unexpected
The six surprises people run into most, and what each one means.
No address found
The name has no A or AAAA record. It may be new, parked, used only for email, or the site may live on www. Try the www version too.
The owner is Cloudflare or another CDN
The domain is behind a CDN or proxy, so DNS shows the CDN's addresses. That is by design and the real server stays hidden.
Different addresses on each check
Load balancing rotates addresses, and CDNs answer by location. All the addresses shown are valid for the name.
The old IP after a DNS change
Resolvers keep the old answer until its TTL runs out. Compare both resolvers, and lower the TTL before planned moves.
Your computer sees another IP
Your device may use your provider's resolver, a VPN, or a hosts file entry. Location-based DNS also answers our server and you differently.
A private or local address
The public name points to an address such as 192.168.x.x or 127.0.0.1, which visitors cannot reach. Usually a leftover test record.
Questions about domain to IP lookups
Why does one domain have several IP addresses?
Busy websites spread visitors over several servers or CDN edge locations. DNS returns all of their addresses and the visitor's device picks one, so if one server is down the others still answer. Seeing two to eight IPv4 addresses for a large site is normal.
Why are there IPv4 addresses but no IPv6?
IPv6 addresses only appear when the domain owner has published AAAA records. Many hosts still offer IPv4 only. The site keeps working for everyone, because devices on IPv6 networks can still reach IPv4 sites through their provider.
Why do I get a different IP when I check again?
Load-balanced sites rotate the order or the set of addresses on each answer, and CDNs may answer differently depending on where the question comes from. After a DNS change, resolvers can also keep the old address until its TTL runs out. The TTL column shows how long each answer may be cached.
Can this tool find the real server behind Cloudflare?
No. When a domain uses a CDN or proxy such as Cloudflare, its public DNS only lists the CDN's addresses, and the network owner shows the CDN company. The website's own server is hidden on purpose. This tool shows what public DNS says and does not try to uncover hidden origins.
What does network owner mean?
It is the organisation the regional internet registry lists for the IP range, read live over RDAP. It is usually the hosting, cloud or CDN company that runs the server, not the owner of the website. A shop on a cloud host shows the cloud company, for example.
How do I find the domain name of an IP address?
That is a reverse lookup, which reads the PTR record of the IP. Enter the IP address in our DNS lookup tool. Many IP addresses, especially on shared hosting and CDNs, have no PTR record or one that names the provider rather than the website.
Are the domains I convert stored?
No. The name you enter is sent from our server to Google Public DNS and/or Cloudflare DNS, and the public IP addresses they return are sent to the regional internet registry to look up their owner. Owner answers are cached per IP for 24 hours without the domain name. A hashed, temporary copy of your IP address is used for rate limiting and expires within 24 hours. Like any website, our server may keep normal access logs, as described in our privacy policy.
