This tool instantly resolves the IP address of any website by its domain name — no technical expertise required. Enter a domain, hit the button, and get full details: IPv4, IPv6, and the reverse DNS hostname (PTR record). It's useful for verifying hosting providers, diagnosing connectivity issues, researching competitors, or checking suspicious websites before trusting them.
How to use the tool
Type a domain name into the field — for example, example.com — and click "Look up". You don't need to include "http://" or "www": the tool handles any format automatically. Within a second you'll see every IP address associated with that domain.
- Enter the domain or URL in the search field.
- Click the check button.
- Review the results: IPv4, IPv6, and the PTR record.
- Use the IP for further hosting research or infrastructure analysis.
What the results show
The tool performs a DNS resolution and returns several types of data:
- IPv4 (A record) — the standard four-block address such as 104.21.45.12. This is what your browser connects to when loading a website.
- IPv6 (AAAA record) — the next-generation address in hexadecimal format. Many modern hosting providers now support both protocols simultaneously.
- PTR record (reverse DNS) — the hostname the server announces when queried in reverse. It often contains the name of the hosting provider or data centre, for example server.digitalocean.com or static.cloudflare.com.
By combining the PTR record and the IP range you can quickly identify the hosting provider, determine whether the site uses a CDN (Cloudflare, Fastly, Akamai), and find out which country the server is physically located in. Learn more in the complete guide to finding a website's IP address.
Frequently asked questions
Why does a domain return multiple IP addresses?
Large websites use load balancing: DNS returns different servers to different users to spread traffic evenly. CDN networks such as Cloudflare also return the node closest to the requester, so the address can vary depending on geographic location.
What is a PTR record and why does it matter?
A PTR (Pointer Record) is a reverse DNS entry that maps an IP address back to a hostname. It is used to verify mail server reputation, diagnose network issues, and identify hosting providers. If the PTR points to a domain like cloudflare.com, the site is behind a CDN; if it points to hetzner.com, it's likely a VPS in Europe.
How do I find the hosting provider from an IP address?
Once you have the IP, you can look up the hosting provider through WHOIS databases such as ARIN, RIPE, or APNIC — they hold registration data for IP ranges. The PTR record often gives you the answer immediately, since most providers embed their name in reverse DNS. This tool surfaces the PTR record automatically.
Is a website's IP different from its mail server IP?
Yes. A website is served via an A record (HTTP/HTTPS traffic), while email is routed via an MX record pointing to a separate server. They can be hosted on entirely different providers with different IP addresses. This tool resolves the web address of the domain only.
