DNS stands for Domain Name System. It acts like the phone book of the internet. When you type a website address (like www.google.com) into your browser, DNS translates that address into an IP address (like 172.217.11.174) that computers use to identify each other on the network.

Here’s a simple analogy:

- Website Name: www.example.com (like a person's name)

- IP Address: 93.184.216.34 (like a phone number)

Just as you use a person's name to find their phone number in a phone book, DNS helps your computer find the IP address associated with a website name.

DNS records are like entries in a directory that tell the DNS system how to handle requests for your domain. Here’s how you can update them:

1. Log In to Your Domain Registrar:

- This is the company where you registered your domain name (like GoDaddy, Namecheap, etc.).

2. Find the DNS Management Section:

- Look for something like “DNS Settings,” “DNS Management,” or “DNS Zone File.”

3. View Existing DNS Records:

- Here, you'll see a list of DNS records that are currently set up for your domain. Common types include:

- A Record: Points your domain to an IP address.

- CNAME Record: Points your domain to another domain name.

- MX Record: Directs email to a mail server.

- TXT Record: Provides text information to sources outside your domain.

4. Add or Edit Records:

- To add a new record, click “Add Record” or a similar button.

- To edit an existing record, click on the record and make the necessary changes.

5. Enter the Details:

- For an A Record, you might enter:

- Name: www

- Type: A

- Value: 93.184.216.34

- For a CNAME Record, you might enter:

- Name: blog

- Type: CNAME

- Value: www.example.com

6. Save Your Changes:

- Make sure to save or apply the changes. This might take a few minutes to propagate (spread) across the internet.

7. Verify the Update:

- After some time, check if your updates are working by typing your domain into your browser or using a DNS lookup tool.

That’s it! You've successfully updated your DNS records.
