In short: To check a domain's DNS records, open a free DNS Record Checker, type the domain, and read the results. It queries live public DNS over secure DNS-over-HTTPS and returns the A, AAAA, MX, TXT, NS and CNAME records instantly, with no software, no account and no cost.

Why check DNS records at all?

You check DNS records to diagnose problems and verify changes. Common reasons: confirming an SPF or DMARC record published correctly, finding out which provider hosts a domain's email (via its MX records), troubleshooting why mail bounces, or auditing a domain before you start sending from it. Because DNS is public, you can do this for your own domain or any other.

How to check DNS records step by step

  1. Open the DNS Record Checker. Go to the free Inboxlogy DNS Record Checker. It runs entirely in your browser.
  2. Enter the domain. Type the bare domain (for example yourdomain.com): no https:// or www needed. The tool cleans the input for you.
  3. Click Check records. It queries live public DNS and returns your A, AAAA, MX, TXT, NS and CNAME records in a few seconds.
  4. Read the results. Each record type is grouped and labelled. MX records are shown in priority order; TXT records include your SPF and any verification strings.
  5. Drill into email records. For SPF, DKIM and DMARC specifically, follow the links to the dedicated checkers for a deeper, plain-English validation.

How to read what the checker shows you

Here's what each record type means at a glance:

  • A / AAAA: the IPv4 / IPv6 address your domain points to.
  • MX: your inbound mail servers; the lowest priority number is tried first.
  • TXT: a catch-all for text records, including your v=spf1 SPF record and domain-verification strings.
  • NS: the authoritative name servers that host your DNS zone (useful for confirming which provider controls your DNS).
  • CNAME: aliases that point one hostname at another (often used for tracking subdomains or DKIM).

What to do if a record is missing or wrong

If an expected record is absent, log in to wherever your DNS is managed (that is the provider shown in your NS records, such as Cloudflare, GoDaddy or your registrar) and add or correct it there. Give it time to propagate (usually under an hour, up to 48 hours), then re-run the checker to confirm. For email specifically, use the SPF, DMARC and DKIM generators to produce correct records before you publish them.

Frequently asked questions

Do I need to install anything to check DNS records?
No. A browser-based DNS Record Checker queries live DNS directly from your browser using DNS-over-HTTPS. There's nothing to install and no command line required.
Is it free to check DNS records?
Yes, completely free with no sign-up. The Inboxlogy DNS Record Checker uses free public DNS resolvers (Google and Cloudflare) and never charges or asks for an account.
Why do I see multiple TXT records?
A domain can have many TXT records: one for SPF (starting v=spf1), plus domain-verification strings for services like Google, Microsoft, Facebook and others. Only one of them should be your SPF record; having two SPF records is an error.
Can I check DNS records on my phone?
Yes. The tool is a responsive web page, so it works on mobile browsers exactly as it does on desktop, which is handy for quick checks on the go.
