Your website is down. Your emails aren’t delivering. A developer is asking you to “check your DNS records” and you’re not sure where to start.

Knowing how to check domain DNS records is one of the most practical skills a website owner can have. It helps you diagnose problems fast, verify configurations, and hand off accurate information to your hosting or email provider. This guide walks you through everything, from what DNS records actually are to how to read and fix them.

What Are DNS Records?

DNS stands for Domain Name System. It’s the internet’s address book, the system that translates a domain name like “yourbusiness.com” into an IP address that servers can understand and route traffic to.

What DNS Records Do

DNS records are instructions stored in your domain’s zone file. They tell the internet where your website is hosted, where to send your emails, and how to verify your domain with third-party services.

How DNS Works

When someone types your domain into a browser, their device queries a DNS server. That server reads your DNS records and routes the request to the right destination. The whole process takes milliseconds.

Why DNS Records Matter

Incorrect or missing DNS records are behind most website outages, email delivery failures, and domain verification problems. Checking your DNS settings is always the right first step when something isn’t working.

Common Types of DNS Records

Record Type	What It Does
A Record	Points your domain to an IPv4 address (your web server)
AAAA Record	Same as A record but for IPv6 addresses
CNAME Record	Creates an alias pointing one domain to another
MX Record	Directs email to your mail server
TXT Record	Stores text data used for SPF, DKIM, and domain verification
NS Record	Identifies the nameservers managing your DNS
SRV Record	Specifies a server for specific services like VoIP
PTR Record	Reverse DNS, maps an IP address back to a domain name

Why You May Need to Check DNS Records

You don’t need to be a developer to check DNS records. Here are the most common situations where it becomes necessary.

• Connecting a domain to web hosting. After registering a domain, you need to point it to your host’s server using the correct A record or nameservers.
• Setting up business email. Email services like Google Workspace or Microsoft 365 require specific MX and TXT records to function correctly.
• Troubleshooting website issues. If your site is down or loading incorrectly, checking your A record and nameservers is the fastest way to identify the problem.
• Verifying domain ownership. Many platforms ask you to add a TXT record to prove you control the domain before activating a service.
• Configuring SSL certificates. Some SSL providers require DNS verification via a CNAME or TXT record.
• Migrating a website. Moving to a new host means updating your A record and potentially your nameservers to point to the new server.

How to Check Domain DNS Records

There are four main ways to check your DNS records. Each one works slightly differently and gives you different levels of detail.

1) Use an Online DNS Lookup Tool

The easiest method for most people. Go to a DNS lookup tool, enter your domain name, select the record type you want to check, and hit search. You’ll see all the current records returned instantly.

DNSChecker.org is one of the most popular options. It shows your DNS records from multiple locations around the world simultaneously, which is useful for checking DNS propagation after a recent change.

2) Use the Command Prompt (Windows)

If you prefer working from the command line, Windows has built-in tools.

nslookup Open Command Prompt and type:

nslookup yourdomain.com

This returns the A record by default. To check a specific record type:

nslookup -type=MX yourdomain.com

Replace MX with any record type: A, CNAME, TXT, NS.

ping

ping yourdomain.com

This shows the IP address your domain currently resolves to. It’s a quick check to confirm your A record is pointing to the right server.

3) Use Terminal (macOS and Linux)

Mac and Linux users have more powerful command-line tools available.

dig (most detailed output)

dig yourdomain.com A

Replace A with any record type. To see all records at once:

dig yourdomain.com ANY

host (simpler output)

host yourdomain.com

Returns the A record, MX records, and basic information in a clean, readable format.

nslookup (also available on Mac/Linux)

nslookup yourdomain.com

Works the same way as on Windows.

4) Check DNS Records from Your Domain Registrar

Log into your domain registrar or hosting control panel. Navigate to the DNS settings or DNS Zone Editor for your domain. This shows all your current DNS records in one place and lets you edit them directly.

Truehost’s DNS management panel makes it easy to view, add, edit, and delete DNS records without needing command-line tools. This is the most beginner-friendly option for managing your DNS settings.

Here’s what to look for when reviewing each record type.

A Record Shows the IP address your domain points to. Example:

yourdomain.com    A    192.168.1.1

If this IP doesn’t match your web host’s server IP, your site won’t load correctly.

CNAME Record Points one subdomain to another domain. Example:

www.yourdomain.com    CNAME    yourdomain.com

This ensures visitors reach your site whether they type “www” or not.

MX Record Directs email to your mail server. Example:

yourdomain.com    MX    10    mail.yourdomain.com

The number (10) is the priority. Lower numbers are tried first. Missing or incorrect MX records mean no email delivery.

TXT Record Contains text data used for verification and email authentication. Example:

yourdomain.com    TXT    "v=spf1 include:_spf.google.com ~all"

This is an SPF record telling email servers which servers are allowed to send email on your behalf.

Nameservers (NS Records) These tell the internet which servers are authoritative for your domain’s DNS. Example:

yourdomain.com    NS    ns1.truehost.com
yourdomain.com    NS    ns2.truehost.com

If your nameservers are pointing to the wrong provider, none of your other DNS records will take effect.

Common DNS Problems and How to Fix Them

1. Incorrect A record. Your domain is pointing to the wrong IP address. Fix it by updating the A record in your DNS settings to your host’s current server IP.
2. Wrong nameservers. If you’ve moved to a new host but haven’t updated your nameservers, your DNS records won’t be read from the right place. Update your nameservers through your domain registrar to point to your current host.
3. Missing MX records. No MX records means no email delivery. Add the correct MX records provided by your email hosting provider.
4. DNS propagation delays. After any DNS change, it can take between a few minutes and 48 hours for the update to spread across all DNS servers worldwide. This is normal. Use WhatsMyDNS.net to monitor propagation progress in real time.
5. Incorrect CNAME records. A misconfigured CNAME often causes broken subdomains or failed SSL verification. Double-check that the CNAME value exactly matches what your service provider requires.
6. Email delivery problems. Usually caused by missing or incorrect SPF, DKIM, or DMARC TXT records. Verify these with your email provider and add any missing records to your DNS zone.
