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
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).
