Every domain name points to at least one IP address, and a domain to IP lookup shows you which. Kwebby's Domain Into IP tool takes a domain or URL, runs a real-time DNS lookup and lists every IPv4 and IPv6 address it returns. Use it to confirm a DNS change, spot a CDN or find the server address before you test a connection.
This guide explains what the results mean, why a domain can return several addresses, and how to avoid the common mistakes.
Key Takeaways
- Kwebby's Domain Into IP tool converts a domain name or URL to its IPv4 and IPv6 addresses with a real-time DNS lookup.
- IPv4 addresses come from A records and IPv6 addresses come from AAAA records, and a domain can have more than one of each.
- Sites on a CDN or with load balancing can return several addresses, and those addresses belong to the CDN or load balancer, not always to the host.
- Two domains on the same IP do not always share one server, because shared hosting and CDNs put many sites behind an address.
- DNS changes appear as cached records expire, which depends on each record's TTL, not on a fixed 24 to 48 hour clock.
- Follow up with Find DNS Records, the Reverse IP Domain Checker or the Domain Hosting Checker for the next question.
What Is the Kwebby Domain Into IP Tool?
Kwebby's Domain Into IP tool is a free tool that converts a domain name to its IP address. Enter a domain such as google.com, or a URL such as https://example.com, and press Lookup. It performs a real-time DNS lookup and returns every IPv4 and IPv6 address the domain resolves to.
You do not need an account, and you can enter the domain with or without www.
Key Features and How It Works
The tool asks DNS the same question a browser asks before it loads a page. Browsers use names, but networks route by numbers, so DNS translates one into the other. The Developer Tools group has more checks like it.
Real-Time DNS Lookup
The tool runs the lookup when you press Lookup, through the recursive DNS resolver on Kwebby's server. That resolver may hold a cached answer until the record's TTL expires, so right after a change the result can still show the old address for a while. Run it again later, or query the domain's authoritative nameserver with dig, if you need the newest answer at once.
IPv4 and IPv6 Addresses
An A record holds an IPv4 address, and an AAAA record holds an IPv6 address, according to Cloudflare's DNS reference. The tool shows both. IPv4 uses 32 bits, which allows about 4.3 billion addresses, and IPv6 uses 128 bits, which was created to solve IPv4 exhaustion.
Several Addresses for One Domain
A domain can have more than one A record. Cloudflare notes that most sites have just one, but some use several for round-robin load balancing across servers with the same content. When a domain sits behind a CDN, you may see addresses that belong to the CDN.
CNAME Aliases
If the name is a CNAME alias, the tool follows the alias to the final A and AAAA records and names the first CNAME target above the results, for example a CDN hostname. It does not list every step of a longer CNAME chain; use Find DNS Records to see each record.
Domain or URL Input
You can paste a full URL or just the domain. The tool keeps the host name and ignores the scheme, path, query and port, so https://example.com:8443/page looks up example.com.
Why a Domain to IP Lookup Matters
A domain's IP address shows where the name points right now, which is the fact you need for most DNS and hosting tasks. After you move a site, the address tells you whether the old or new server answers. When something breaks, it tells you which machine to investigate.
Common reasons to look up an address include:
- Verifying DNS changes after you change an A record or nameservers.
- Investigating hosting to learn which network a site lives on.
- Comparing sites to see whether two domains point to the same address.
- Testing connectivity to a server by its address.
- Locating a server by pairing the IP with geolocation.
How to Use the Domain Into IP Tool
Follow these steps to look up one domain.
- Enter the domain or URL. Type a name such as google.com, or a URL such as https://example.com, into the box.
- Press Lookup. The tool runs a real-time DNS lookup.
- Read the IPv4 addresses. These come from the domain's A records.
- Read the IPv6 addresses. These come from the domain's AAAA records.
- Count the results. More than one address suggests load balancing or a CDN.
- Follow up. Use the Reverse IP Domain Checker or Domain Hosting Checker to learn more about an address.
If a lookup fails, use the "Report if not working" button on the page. You can also check from a terminal: run nslookup example.com on Windows, or dig example.com A on Mac and Linux.
Best Practices for Domain to IP Lookups
An IP address is a clue about infrastructure, not a verdict. These habits keep your conclusions accurate.
Expect DNS Changes to Take Time
Resolvers keep answers in cache until a record's TTL runs out. Cloudflare's explanation of TTL says shorter values let changes take effect faster and longer values delay them. So there is no fixed 24 to 48 hour rule. Before a migration, lower the TTL, make the change, then look the domain up again later.
Do Not Assume Shared IP Means Shared Server
Two domains on the same address might share a server, or they might sit behind the same CDN or load balancer. The Reverse IP Domain Checker lists other domains that resolve to an address, which is a lead worth confirming with another source.
Treat CDN Addresses as the CDN
If the address belongs to a CDN, you are looking at the front door, not the origin server. To learn who runs the site, use the Domain Hosting Checker and read the nameservers and registrar as well.
Remember That Geolocation Is Approximate
An IP address maps to a location only roughly. The Bulk GEO IP Locator locates many addresses at once, but treat the result as an estimate, particularly for CDN addresses.
Look at the Whole Record Set
An address is one piece of a domain's DNS. Find DNS Records shows the other records of the domain, and the WHOIS Checker adds the registration record.
Common Use Cases
- After a hosting move. Confirm that the domain now points to the new server.
- Firewall and allowlist work. Find the address you need to permit or block, then check it again later, since addresses change.
- Troubleshooting. Check whether a domain resolves at all when a site will not load.
- Competitor and hosting research. See where a rival's site points.
- Developer testing. Get the address of a staging server for connection tests.

Frequently Asked Questions (FAQs)
How do I convert a domain to an IP address?
Enter the domain or URL in the Kwebby Domain Into IP tool and press Lookup. The tool runs a real-time DNS lookup and lists every IPv4 and IPv6 address. You can also run nslookup or dig in a terminal.
How do I point a domain to an IP address?
Create an A record at your DNS provider with the server's IPv4 address, and an AAAA record for an IPv6 address. The change shows up as cached answers expire, which depends on the record's TTL. Look the domain up again afterwards to confirm.
Why does a domain return more than one IP address?
A domain can have several A or AAAA records. Sites use them for load balancing, and CDNs return their own addresses. Both mean the addresses are not always the origin server.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses, with room for about 4.3 billion. IPv6 uses 128-bit addresses and was created because IPv4 addresses are running out. The tool shows both when a domain has them.
How long does a DNS change take to show?
It depends on the record's TTL and on how resolvers cache the old answer. Shorter TTLs let changes appear faster. The lookup shows what Kwebby's resolver currently returns, which can be a cached answer until the TTL runs out.
Is the Kwebby Domain Into IP tool free?
Yes. The Domain Into IP tool is free to use and needs no account.
Final Thoughts
A domain to IP lookup takes seconds and answers a basic question: where does this name point right now? Run it after any DNS change, read the result as a lead and confirm bigger conclusions with a second tool.
Try the lookup on your own domain, then open Find DNS Records to see the rest of its setup. If you need help with hosting or DNS for a new site, Kwebby's development services can help.
