# Free DNS Lookup Tool (A, MX, TXT, NS…)

> Paste a domain to resolve A, AAAA, CNAME, MX, NS, TXT, and SOA records. Handy for domain moves, email setup, and verifying DNS before launch.

```yaml
url: "https://www.scrolllaunch.com/tools/dns-lookup"
slug: dns-lookup
category: onpage
keywords: "dns lookup, dns checker, mx lookup, txt record lookup, a record lookup, free dns lookup"
```

## How to use

1. **Enter a domain** - Paste example.com (or a full URL - we use the hostname).
2. **Resolve records** - We query public DNS for A, AAAA, CNAME, MX, NS, TXT, and SOA.
3. **Verify changes** - After DNS edits, wait for TTL and look up again before launching.

## When founders need a DNS lookup

Before pointing a custom domain at Vercel/Cloudflare, confirm A/CNAME targets and that old records are gone.

TXT records prove domain ownership for Google, Resend, and many SaaS tools - look them up here after you add them.

Pair DNS checks with the SSL checker once HTTPS is live.

## What you get

- A / AAAA / CNAME records
- MX + NS + SOA
- TXT records (SPF/DKIM hints)
- Instant public DNS lookup
