Checking DNS Records for a Domain
Overview
DNS (Domain Name System) is the internet's address book — it maps a domain like example.com to the servers that host its website, email, and services. A DNS checker looks up a domain's records so you can confirm they're set correctly, diagnose why a site or email isn't working, or verify a change has propagated. This tool queries the records and shows them in a clear, readable form.
How to Use (Step by Step)
- 1
Enter the domain
Type the domain name you want to inspect, without http:// or a path.
- 2
Pick a record type
Choose A, MX, TXT, CNAME, NS, or another type depending on what you're checking.
- 3
Read the records
Review the returned values and compare them against your intended configuration.
How It Works
You enter a domain and choose a record type — A and AAAA point to IP addresses, MX routes email, CNAME creates aliases, TXT holds verification and policy data like SPF and DKIM, and NS lists the authoritative name servers. The checker queries public DNS and displays the returned records along with their values, so you can compare them against what you expect.
When to Use This
Confirming a new website's A record points to the right server. Checking MX records when email isn't being delivered. Verifying a domain-ownership TXT record for a service like Google or a mail provider. Watching a DNS change propagate after updating your registrar. Diagnosing why a subdomain doesn't resolve. Auditing SPF and DKIM records for email deliverability.
Frequently Asked Questions
DNS records are cached for a period set by their TTL (time to live). After a change, old values can linger in caches until the TTL expires — often minutes to hours — before the new record is seen everywhere.
Important Notes
Results reflect what public DNS returns at that moment and from that resolver — propagation and caching mean different locations may briefly see different values. Always allow time after a change before concluding something is broken.
