DNS A record

A DNS A record (Address Record) is a fundamental DNS (Domain Name System) record that maps a domain name to an IPv4 address. It allows users to access websites using easy-to-remember domain names instead of numerical IP addresses.

Example of an A Record:

Hostname: example.com

Record Type: A

IP Address: 192.168.1.1

TTL: 3600 (Time to Live, in seconds)

✅ This means when someone enters example.com in their browser, it will resolve to the IP address 192.168.1.1.

How It Works:

A user types example.com in a web browser.

The browser queries a DNS resolver to find the IP address for example.com.

The resolver checks the A record and returns the IP 192.168.1.1.

The browser connects to that IP address to load the website.

When to Use an A Record:

To point your domain to a web server with a static IPv4 address.

For setting up nameservers (ns1.example.com → 192.168.1.1).

To create subdomains (blog.example.com → 192.168.1.2).
