IP Lookup

Resolve a domain to its IPv4 / IPv6 addresses, list its DNS records (MX, NS, TXT, SOA, CAA), do a reverse-DNS check on each IP, and look up the geographic location and ASN that owns it. You can also enter a raw IP address.

What an IP Lookup Tells You

When you type a website name into your browser, something invisible happens behind the scenes: your device asks the internet, “What is the actual address for this site?” That address is called an IP address. Think of it like a phone number for a computer on the internet. Every website, email server, and online service has one — or often several.

An IP lookup takes a domain name (like example.com) or a raw IP address and shows you what is connected to it. The IP address behind a domain reveals a surprising amount of useful information: the cloud provider hosting it, the country and city of the data centre, the ASN (autonomous system) that owns the network, and — through reverse DNS — sometimes the original hosting customer. For SEO and competitive research, that data is gold. For everyday users, it is simply a fast way to understand who is really running a website before you trust it, buy from it, or troubleshoot a problem.

You do not need to be a programmer to use this tool. Type any domain or IP into the search box above and we handle the technical work. The sections below explain what you are looking at in plain language.

How Does a Domain Name Become an IP Address?

Humans remember names; computers remember numbers. The system that translates between them is called DNS (Domain Name System). When you visit a site, your browser quietly asks a DNS server: “What IP belongs to this name?” The answer comes back in milliseconds and your browser connects to that address.

DNS is not just one answer. A domain can have many records at once — some for web traffic, some for email, some for security checks. That is why a full IP lookup is more useful than simply pinging a site. You see the whole picture, not just the front door.

What We Resolve

We do a full DNS sweep of A, AAAA, NS, MX, TXT, SOA, and CAA records. Here is what each one means in everyday terms:

  • A and AAAA records— the main “where is this website?” answers. A records point to older-style IPv4 addresses (four numbers like 93.184.216.34). AAAA records point to newer IPv6 addresses, which look longer and use letters and numbers.
  • NS records— show whose DNS is authoritative. Common names you might see include Cloudflare, AWS Route 53, or Google Cloud DNS. This tells you who manages the domain's settings.
  • MX records — show the email provider. If a business uses Google Workspace or Microsoft 365, you will usually see it here.
  • TXT records — short text notes attached to a domain. The TXT list often reveals SPF, DKIM, DMARC, and verification records (Google, Microsoft, Atlassian, etc.) that hint at which third-party tools the site uses. SPF and DMARC help prove that email from that domain is legitimate and not spoofed.
  • CNAME records — aliases that point one name at another. Many CDNs and website builders use these so you only need to update one place when things change.
  • SOA records — technical housekeeping for the domain zone, including how often DNS caches should refresh.
  • CAA records — a security setting that limits which companies are allowed to issue SSL certificates for the domain.

Together, these records paint a clear picture of how a site is set up — not just where it lives, but how email is handled, which services are connected, and how seriously the owner takes security.

Reading Your Results: A Simple Walkthrough

After you run a lookup, you will see a summary banner at the top showing how many records were found. Below that, each IP address gets its own card with location details, timezone, coordinates, and the organisation that owns the network block.

Country and city tell you roughly where the server appears to be located. ASN (Autonomous System Number) identifies the network operator — for example Amazon, Google, or a local internet provider. Organisation is the company name tied to that network. Reverse DNS shows whether the IP maps back to a readable hostname, which is especially important for email servers.

If something looks wrong — say your own site still points to an old host after a move — compare the IP addresses here with what your hosting company gave you. Mismatches are one of the most common reasons a website or email stops working after a migration.

IPv4 and IPv6: Why There Are Two Kinds of Address

The internet originally used IPv4, which provides about 4.3 billion unique addresses. That sounds like a lot, but the world ran out years ago. IPv6 was introduced to solve the shortage and can support an almost unlimited number of addresses. You can read a friendly overview on Cloudflare's IPv6 guide.

Most modern websites support both. If you only see IPv4 addresses for a site, it may still work fine for most visitors today — but IPv6-only networks (common on some mobile carriers) could have trouble. Seeing both A and AAAA records is generally a sign of a well-maintained setup.

What Is Reverse DNS and Why Does It Matter?

Normal DNS answers the question: “What IP does this domain name point to?” Reverse DNS flips that around: “What domain name is registered for this IP?” This is done with a special record type called a PTR record.

For most casual browsing, reverse DNS does not affect you. But if you send email from your own server, missing or incorrect reverse DNS is a common reason messages land in spam. Many businesses check it automatically. It is also useful when a site sits behind a CDN: the forward address might show Cloudflare, but reverse DNS on the origin IP can reveal the real hosting company underneath.

Geolocation Accuracy

IP geolocation is approximate. It is based on registries that map IP blocks to network owners; for cloud and CDN IPs the location reported is usually the closest data centre rather than where the company is registered. Anycast networks (Cloudflare, Fastly, AWS CloudFront) will resolve to whichever PoP (point of presence) happens to be closest to our server, not yours.

In practice, this means country-level results are usually trustworthy, but city-level results can be off by hundreds of kilometres — especially for large cloud providers with data centres everywhere. Coordinates on the result card are estimates, not a GPS pin on someone's office. Use them as a rough guide, not as proof of where a person or business physically sits.

If you need to understand why results differ between tools, IP geolocation works by matching address ranges to databases that are updated regularly but never perfectly.

Everyday Reasons People Use IP Lookup

You do not need a technical background to get real value from this page. Here are situations where a quick lookup saves time:

  • Checking a suspicious link — before clicking an unfamiliar shop or login page, see whether it points to a reputable host or something unexpected.
  • After moving your website — confirm your domain now points to the new server and the old IP is gone.
  • Email problems — inspect MX and TXT records to see if mail is routed correctly and authentication is configured.
  • Comparing competitors — notice when a rival switches from shared hosting to a CDN or cloud platform.
  • Understanding downtime — if a site is down, checking whether its IP changed can tell you if DNS was updated incorrectly.
  • Verifying your own setup — small business owners often inherit DNS settings from a web designer; this tool shows exactly what is live right now.

What IP Lookup Cannot Tell You

It is equally important to know the limits. An IP lookup will not show you private information about individual visitors, exact street addresses, or who owns a website legally — only where the server appears to be hosted. Two completely unrelated websites can share the same IP on budget shared hosting. A company in London might host its site in Frankfurt because that data centre is faster or cheaper.

Privacy tools, VPNs, and proxy services deliberately hide a user's real location, so never use IP data alone to make serious legal or security decisions. Treat this tool as an infrastructure map, not a detective dossier.
