I Built a Free Tool to Look Up IP Addresses and Analyze DNS Records

Astro Stack — Tue, 20 Oct 2026 09:50:13 +0000

As a developer, I often need to check a domain's IP address, inspect DNS records, troubleshoot email configuration, or investigate why a website isn't resolving correctly.

These tasks are simple individually, but switching between different tools can make the workflow unnecessarily slow.

That's why I built DomainToIPTrace — a web-based toolkit for domain and DNS analysis.

What can you do with DomainToIPTrace?

1. Find a domain's IP address

Enter a domain name to look up its public IPv4 and IPv6 addresses.

This is useful when troubleshooting DNS resolution, checking hosting configurations, or investigating where a domain resolves.

2. Analyze multiple domains at once

Working with a list of domains? Bulk lookup helps you process multiple domains without checking each one manually.

This can be useful for developers managing multiple websites, system administrators maintaining infrastructure, and SEO professionals researching domain lists.

3. Inspect DNS records

DNS records provide important information about how a domain works.

With DomainToIPTrace, you can investigate supported record types, including:

A and AAAA: IPv4 and IPv6 addresses
MX: Mail server configuration
NS: Authoritative nameservers
TXT: Text records, including email verification and policy records
CNAME: Domain aliases
SOA: DNS zone information
CAA: Certificate authority restrictions

These records can help you diagnose misconfigurations and better understand a domain's DNS setup.

4. Troubleshoot email DNS configuration

Email delivery problems can sometimes be related to DNS configuration.

Checking MX, SPF, and DMARC records helps you investigate whether the expected mail-related records are present and configured as intended.

Keep in mind that checking these records alone does not guarantee successful email delivery or complete email security.

5. Use additional network utilities

Depending on the task, you can also use reverse DNS lookup and subnet calculation tools to investigate IP addresses and network ranges.

These are useful additions when you're troubleshooting hosting or networking issues.

6. Export results for further analysis

For workflows involving multiple domains, downloadable CSV and JSON results can make it easier to review findings, share reports, or process data with scripts.

Who might find this useful?

DomainToIPTrace is designed for people who regularly work with domains and network infrastructure, including:

Web developers
DevOps engineers
System administrators
Hosting providers
SEO professionals
Security researchers
Website owners

Why I built it

I wanted to bring common domain lookup and DNS investigation tasks into one accessible interface instead of making users jump between multiple utilities.

The goal is straightforward: make routine domain research and troubleshooting easier, whether you're checking one domain or working with a larger list.

I'd love your feedback

If you work with DNS, domain infrastructure, or website troubleshooting, I'd like to hear from you.

What domain or networking utility would you find most useful to have in one place? What would you improve or add?

Your feedback can help shape what comes next.
