Domain to IP Lookup

Find the current IP address of a domain (IPv4 and IPv6) and its reverse PTR record.

How to find a website's IP address

The tool resolves the IP address a domain points to: it shows the IPv4 address, the IPv6 address when one exists, and the reverse PTR record for the address found. It is a quick way to see where a site actually answers and to tie a domain name to a specific server. The result is useful when setting up infrastructure, troubleshooting availability and managing access lists.

Why you might need a site's IP

  • Firewall rules: allow or restrict access to a specific server address.
  • Allowlists: add the IP to the permitted list for an API, control panel or mail relay.
  • Troubleshooting: check that the server responds and compare the address with what you expect after a migration.
  • Routing: confirm the domain points to the right machine, not your old host.

Why the IP may not be your actual server

The address shown does not always belong to your server directly. If the site runs behind a CDN or a DDoS protection service, the domain points to that network's address rather than the origin server. In that case the IP belongs to the service's infrastructure and the real server sits behind it. That is a standard setup for speed and protection; to see who owns an address, try the hosting checker.

What PTR is and why email needs it

A reverse PTR record maps an IP address back to a hostname, the opposite of a regular A record. It matters most for mail servers: receiving servers check that the sender's IP has a valid reverse record, and when it is missing or mismatched, messages are more likely to be flagged as spam or rejected. If you run your own mail server, make sure your provider has set a valid PTR for its IP; most VPS providers let you edit it in the control panel.

Frequently asked questions

What does the tool show for a domain?
The IPv4 address, the IPv6 address if there is one, and the reverse PTR record for the address found.
Why does the IP not match my server?
If the site runs through a CDN or a protection service, the domain points to that network's address and the origin server stays hidden behind it.
What is a PTR record?
It is a reverse DNS record that maps an IP address to a hostname, the opposite of a regular A record.
Why does email need a PTR record?
Receiving mail servers check the sender's PTR record, and messages from IPs without a valid one are more likely to end up in spam.
How can I use a site's IP in practice?
It is useful for firewall rules, allowlists and troubleshooting server availability.
Can a domain have more than one IP?
Yes. A domain can answer on several addresses to spread load, including separate IPv4 and IPv6 addresses.
