5 Advantages and Disadvantages of Domain Name System | Risks & Benefits of Domain Name System (DNS)

 

DNS: What is it?

One type of computer server that has access to an entire database of IP addresses is the Domain Name System (DNS). Put otherwise, it's a hierarchical naming scheme that allows users connected to the same network to access other devices or computers.

How is DNS operated?

In essence, the DNS server receives the request from the user when they type in the URL rather than the Google server. These DNS servers employ lookup tables to determine whether the response is cached on the machine. 

If not, the request is sent to the appropriate servers so that the user's web browser displays accurate information. It makes use of two DNS servers for this. The Primary and Secondary are those.

What use does DNS serve?

Without having to type IP addresses, DNS facilitates connections to search engines. It also has additional important capabilities that site managers frequently utilize. In order to prevent attackers from taking advantage of DNS usage, users must be aware of these serious vulnerabilities.


I will be discussing the 5 Advantages and Disadvantages of Domain Name System  | Risks & Benefits of Domain Name System (DNS). You will learn about the pros and cons of DNS use from this post.

Now let's get started,

 

Advantages of DNS

1. Internet Dependency

The internet has grown to be such an integral part of our daily lives that businesses and individuals cannot function without it. Because DNS remembers all of the IP addresses, using the internet is much easy. In actuality, the internet would not exist without DNS.


2. Internet Speed

High-speed connection speeds are one of DNS's primary benefits. Most users of this speed are individuals and organizations.


3. Security

Certain DNS servers are created with security in mind, to the point that they are now necessary for connections at home or at work. Hackers are unable to access your systems whenever they attempt to breach the servers. 

 

However, additional security precautions are required if the organization is large and contains a lot of sensitive information.


4. IP Address Conversion

Users can archive and classify search terms using DNS without having to remember IP addresses. When the name is submitted to search engines, all domains are transformed into IP addresses. 

 

As a result, you don't have to commit the IP address of every website you visit on a regular basis to memory.


5. Stability

Websites may experience IP address changes for several reasons. Therefore, users must also stay current with this information. This can be an extremely taxing task. However, in order to make this easier for users, the DNS system refreshes IP addresses on a regular basis. 

 

 

Disadvantages of DNS

1. Registry Control

ICANN is in charge of DNS registry management. which implies that they will be immune to control by other organizations. Therefore, the idea of net neutrality is called into doubt here. ICANN is a well-known non-profit organization with a single nation of origin.


2. Client Information

DNS queries often do not carry information about the client who initiated the name resolution. As a result, the IP address of DNS servers will be known to the server side. Hackers are capable of manipulating it.


3. Server Breakdown

The World Wide Web would also crash if the DNS server went down. even with backup servers and primary servers present. This is due to the fact that when a server crashes, the local network connection is severed, making it impossible for clients to contact the server.


4. DNS Attacks

The DNS attack is one of the main issues that DNS faces. Here, a fake DNS address is used in place of the actual one to route viewers to phony websites. Attackers may obtain private information, including band account information, from this.


5. Troubleshooting

Most DNS problems are hard to troubleshoot. Its dispersed nature and geographic locations are to blame for this.
