GeoDNS service – Everything you need to know

With GeoDNS service, you can accomplish remarkable results and drop the waiting time for your clients based on their location. No matter where your users are placed in the world, you can make your domain resolution much faster for them.

What does GeoDNS service mean?

GeoDNS service is usually a paid feature that can be found in the portfolio of the bigger DNS providers. Its purpose is to determine where are the users’ IP addresses. Afterward, it points them to the nearest server. Thus, it is often applied as a geographical routing method, which can assist with reducing the stress on an individual server. In addition, it routes the traffic to several servers, and it is a load balancer.

If your business has a worldwide presence and you desire to provide better performance to your clients, you should consider a GeoDNS service. It will ensure an excellent experience for the visitor of your website.

How does it function?

If you want to use the GeoDNS service, you will have to find a DNS provider supporting Geolocation. After you implement it and a user’s query is received, the DNS server will search for its location. That happens through the user’s IP address. DNS reviews it, and it will scan in the database for the location. Then the name server assigns a pre-configured record, which is defined explicitly for the region from where the query comes from.

When once GeoDNS identifies the location of the query, it will respond with a record configured especially for its location .

To send visitors to the best server and closest location, it uses DNS GeoIP searches. So, all servers will hold several IP addresses for the identical domain.

For who is it intended?

All kinds of businesses can benefit from GeoDNS. Small websites that want to grow also probably would like to have it. The biggest need for operating things smoothly would be for large companies.

There is a group of companies that can get the most out of it. For example, international organizations handle significant amounts of traffic or content platforms, which need to deliver to a global audience, and e-commerce, which are always seeking high uptime to secure profits.

Why is it beneficial to use the GeoDNS service?

When you set up a GeoDNS service, a lot of benefits will influence your business.

Moreover: 

  • It is not complicated to configure GeoDNS.
  • Better SEO, faster response and loading time, 100% uptime, and higher speed are key benefits.
  • You have more choices, and it is easier to manage the traffic. By setting some records on the DNS control panel, you can direct traffic to a local country or a different state.
  • With GeoDNS, you can set limits or break them to access the content. So your visitors are going to be capable of reaching your content, no matter their location.
  • Your website is going to be available and not disrupt by any maintenance or daily tasks. Even shutting down a server to update it or change it is not a problem. You have many options to serve all requests and to re-direct the traffic.
  • Congestion on particular network points is going to be finally avoided.

Fully Qualified Domain Name (FQDN) explained.

What is FQDN?

FQDN is the short acronym for Fully Qualified Domain Name. With it, you are able to see precisely the most full name of a specific domain name. And that refers not only to websites but also to servers. The Domain Name System (DNS) is created with a hierarchy order. It starts from the top, which is the root, then TLD, after that the domain, and the last is the specific hostname.

Here is the full syntax of a fully qualified domain name (FQDN):

hostname. domain name. TLD 

([hostname].[domain].[tld].)

Let’s view an example of a fully qualified domain name (FQDN):

mail.google.com. 

movies.disney.com.

ftp.microsoft.com. 

Be aware that the dot “.” (root), which is last, is often neglected. Usually, the fully qualified domain names end with the TLD. However, there are cases in which you will need to add it. That depends on what software you are using.

The Fully Qualified Domain Name is suitable when you want to view where precisely an object exists in the Domain Name System hierarchy.

Elements 

Here are the 3 elements of Fully Qualified Domain Name formatting. 

  • First is the TLD (Top Level Domain) – It is represented with the ending signs that we can see in an FQDN. Commonly 2 or 3 characters, such as .com, .edu, .net etc.
  • Subdomain – It is the domain that we can observe below the Top Level Domain. For example, Domain.com.
  • Hostname – It is represented with the symbols placed at the beginning of the FQDN. The most popular example is www in www.domain.com. A domain owner can generate many hostnames as they are associated with a subdomain. For example:
    • ftp.domain.com
    • mail.domain.com
    • www.domain.com

How to check the FQDN?

If you want to check if your device has an FQDN or its hostname is an easy task. It doesn’t matter if you are using a Windows 10, Linux, or macOS device. 

On Windows 10

  1. From the start menu, open your “Control Panel.” 
  2. Inside the Control Panel, open the System. 
  3. Inside the System, view the “Device specifications” and search for the “Device name”. 
  4. Next is the FQDN. 

On Linux 

  1. First, open the Terminal application. 
  2. Simply write this command: “hostname -f.”
  3. Press Enter, and you will see the FQDN. 

On macOS:

  1. First, open the Terminal application.
  2. Write down the command: “hostname -f.” The option “-f” means full. 
  3. Press the Enter, and you will see the FQDN. 

Why do you need FQDN?

The FQDN represents a unique address on the Internet. It is vital to the experience online. Imagine it, like you don’t have an FQDN. It is like you don’t have a website for people to visit. 

You will need FQDN if you want to install SSL certificates. This is because most websites are expected to have such a feature. 

With FQDN, you can access domain services, for example like email and File Transfer Protocol (FTP). If you want to connect a domain name email to an email app on your device manually, you will need the FQDN.
