DNS Records

DNS records (Domain Name System) are like your phone's contact list, but for the internet. They translate domain names (like "google.com") into IP addresses, which are numbers that identify computers on the internet (like 192.168.1.1). This allows your browser to find and display the correct website.

How do they work?

When you type a web address into your browser, DNS works like this:

1. DNS query: Your computer asks the DNS server what the IP address is for the domain name you typed.
2. DNS response: The DNS server responds with the correct IP address.
3. Connect to the site: Your browser uses the IP address to connect to the site's server and display the web page to you.

Types of DNS Records

There are several types of DNS records, here are the most common:

1. A record: Translates a domain name into an IP address. Example: "mysite.com" → "192.168.1.1".
2. CNAME record: Points a domain name to another domain name. Example: "blog.mysite.com" → "mysite.com".
3. MX record: Indicates the email servers for a domain. Example: "mail.mysite.com".
4. TXT record: Contains text information for various purposes, such as domain verification.
