# Emailing Host Records

Explaining emailing host records

### **Common DNS Records Explained** 🚀

DNS (Domain Name System) records are like a phone book for the internet. They tell browsers and email services where to go. Here’s a **simple breakdown** of the most important DNS records you might need to know.

When you buy domains from Infraforge/Mailforge they come automatically with DMARC, DKIM, and SPF on purchase

On Mailforge, Infraforge and Primeforge, the MX, SPF, DKIM and DMARC records we add for your mailboxes are locked by default, so you can’t change or delete them yourself. See [Unlock DNS records on Mailforge, Infraforge and Primeforge](https://help.salesforge.ai/en/articles/10333681-unlock-dns-records-on-mailforge-infraforge-and-primeforge.md) to learn why and how to ask support to unlock them.

### **Essential DNS Records**

-   **A Record** – Connects a domain to an **IPv4** address (e.g., `example.com → 192.168.1.1`).
    
-   **AAAA Record** – Same as A, but for **IPv6** addresses.
    
-   **CNAME Record**: Points one domain (alias) to another domain (canonical). Used for subdomains (`blog.example.com → example.com`). Works at the DNS level.
    
-   **MX Record** – Tells email services where to deliver emails.
    
-   **TXT Record** – Stores text info (often used for email security).
    
-   **NS Record** – Lists the name servers managing your domain.
    
-   **URL Record** – **URL Record**: Redirects a domain to a full URL (`oldsite.com → newsite.com`). Changes the browser URL. Used for forwarding.
    

### **Email Security Records (Stops Spam & Spoofing)**

-   **SPF Record** – Defines which mail servers can send emails for your domain. Helps prevent fake emails.
    
-   **DKIM Record** – Adds a **digital signature** to your emails to prove they are legit.
    
-   **DMARC Record** – Tells email servers what to do if an email **fails SPF or DKIM** (reject, spam, or allow).
