The biggest problem is 75% people don’t understand DNS or domain name system, they know little here and there that exactly same situation I was before. To give you a definite answer I already wrote an article on DNS. But here I am giving you a little summary.

What is DNS or domain name system ?

DNS is a system which find the IP Address of a website (domain).
Domain name e.g. www.google.com is just like your smartphone contact name and IP address is like phone number.
Can you call someone with just contact name, of course not you can’t, you need a phone number, just like you need an IP Address to visit a website. There are billions of websites and every hour thousands of new website are created.  The systems which store and manage that huge data of  Domain names and IP addresses is called Domain Name System or DNS.

What is Google Cloud DNS?

On google cloud platform google providing you a service for storing and publishing IP addresses and other records of your Domain. 
Simply putting Google is running a DNS server and you can Store your DNS zone records on their server. And by the way you also can create your own DNS server (not good for performance) click here to know more.

How Google Cloud DNS Work?

DNS Resolver: DNS resolver which you might install in your Windows or Routers Network settings, e.g. google public DNS (8.8.8.8), Open DNS(208.67.222.222) Cloudflare Public DNS(1.1.1.1), your ISP DNS etc. 

When you are trying open a website on your browser, DNS resolver job is to track down the IP records and give it back to you.

DNS Root Nameserver: There are only 13 root nameserver around the world. When the resolver sends a query to DNS root nameserver, the root server then responds to the resolver with the IP address of a Top Level Domain (TLD) DNS server (such as .com or .net or .org), which stores the information for its domains. When searching for example.net, our request is pointed toward the .net TLD nameserver.

DNS TLD Nameserver: The resolver then makes a request to the .net TLD. The TLD server then responds with the IP address of the Google Cloud DNS nameserver, example.net.

You can update TLD nameserver records of your domain by changing nameserver records from your domain registrar website.

Google Cloud DNS: Lastly the resolver makes a request to Google Cloud DNS. And Google Cloud DNS responds with the IP address of your website server.

 This is how Google Cloud DNS works. I hope you understand if not then please place a comment in the comment section below.

Why Google Cloud DNS?

Now you’re thinking why bother using Google Cloud DNS. Yes you are right you don’t need to use it but you should use a fast DNS service for your website. Fast and retaible DNS is good for your site because it decreases  latency and improve SEO of your website. Google Cloud DNS is one of the best DNS Service Provider in this industry. Others are AWS cloud DNS, Cloudflare DNS etc.

Google Cloud DNS Pricing.

Google Cloud DNS will charge you per month  for per zone (per domain name), and you also pay for queries against your zones.

Here the price table of Google Cloud DNS:

How much it will cost to host a website using Google Cloud DNS?

GCP Cloud DNS price is base on two different factors, the numbers of zones and the DNS queries (per month).

You just need one zone for one website. If you want to set up DNS for 5 different domains then you will need 5 zone records. And the DNS queries are proportional to your website monthly visitors.

Here is some typical examples of DNS pricing. 

For a website which has 200000 monthly visitors, Google Cloud DNS  cost will be around $0.28 per month.

Here is an example of a website which has 200000 monthly visitors and also enable personalize CDN service.

E.g. Domain name: example.com

E.g. CDN name cdn.example.com

Then for every page visit you will have two DNS queries. Your Google Cloud DNS price will be $0.36 per month.

  1. Create a new DNS zone on Google Cloud.
  2. Update your TLD Nameserver for your domain registrar website.
  3. Find and copy your web server IP address.
  4. Add your IP address and other records to GCP.

Let’s get started.

Create a New DNS Zone on Google Cloud Platform:

Those are the nameservers which you have to update or modify from your domain registrar website. Copy these NS records one by one. 

Update Your TLD Nameserver.

As you already know, that your domain registrar website is connected to the TLD Nameserver. When you  Change the Nameserver records from your domain registrar site, TLD server also get updated, BUT it can take up to 48 hours.

Here I am showing you how to update your  NS records from GoDaddy and Namecheap website. If your domain registrar is different from those two, then place a comment or search it on Google.

If you register your domain from GoDaddy, then follow the steps below:

Login to your GoDaddy account. Then navigate to Domain Manager >> DNS >> Manage Zones.

Scroll down, Then click on the “Change” button on the Nameservers field.

Select custom DNS and place the nameserver records which you copied from Google Cloud DNS.

Copy your web server IP address:

Many people do not know where to find their web server IP address, Do not worry it happens when you are new in this field. Follow the steps below to Find your web server IP Address.

If you don’t have any web server on Google Cloud, then follow any of those two posts:

Select “A” from the “Resource record type”. Then leave the “DNS name” field empty. Place your web server IP address on the “IPv4 address” field. Lastly click on “Create”.

Just like the previous step, again click on the “Add record set”. Then  type “WWW” in the DNS name field. Place your web server IP on IPv4 address field. Then click on create.

This step is completely optional, only follow it if you have email mail server.

Select  MX from Resource record type field. Then replace the mx1.privateemail.com and  mx2.privateemail.com to your  email server. Lastly leave the DNS name section blank and click on “Create”.
