Understanding Your DNS Results
If you are updating your website or fixing email delivery issues, your IT team or hosting provider will often ask you to check specific records. Here is a quick cheat sheet on what each record does:
What Do These DNS Records Mean?
Registrar Information
This shows the company where the domain name was officially purchased (e.g., GoDaddy, Namecheap, Google Domains) and when it was registered.
A Records (IPv4)
The core of your website. This tells the internet exactly which server IP address your website files live on.
MX Records (Mail Exchange)
This controls your business email. It routes incoming emails to your provider, such as Google Workspace or Microsoft 365.
TXT Records (Text)
Commonly used for domain verification and email security (like SPF, DKIM, and DMARC). If your emails are going to your clients' spam folders, you usually need to update your TXT records.
NS Records (Nameservers)
These act as the "directory" for your domain, telling the internet which provider is currently managing all of your DNS settings (often Cloudflare or your web host).
CNAME (Canonical Name)
Used to alias one name to another, often used for subdomains like shop.yourwebsite.com or www.yourwebsite.com.
