What is DNS?

Ensuring that businesses can securely manage their digital assets depends not only on strong server infrastructures but also on proper network configurations. At this point, DNS, or the Domain Name System, plays a critical role in routing internet traffic. In today’s increasingly complex threat landscape, DNS switching has become a strategic move not only for speed and accessibility but also for security. Here, you will find everything you need to know about DNS switching, which involves directing the DNS server used by devices or networks to a different service provider!

DNS is a system that converts domain names into IP addresses. When a user wants to access a website (for example, www.example.com), DNS translates that domain name into an IP address that the machine can understand. This system is critical not only for fast access to websites, but also for secure data transmission. Click here to find a more detailed answer to your What is DNS question!

Frequently Asked Questions About DNS Switching

DNS switching is the process of directing the DNS server used by devices or networks to a different service provider. The main purposes of switching DNS include improving access speed and stability, bypassing censorship or regional access restrictions, protecting against malware and phishing attacks, and centrally managing corporate network security. At the enterprise level, DNS management is essential not only for maintaining access performance but also for protecting brand digital integrity. When corporate DNS solutions are preferred, malicious redirections are blocked and data leakage is prevented. In addition, access policies can be centrally applied across different departments or offices. It also provides an additional layer of protection against DNS-based DDoS or spoofing attacks. Corporate DNS services operate in integration with cloud-based content delivery networks, reducing application response times. Moreover, most enterprise DNS solutions offer scalability and the ability to add new features based on growing needs.

What Are the DNS Switching Methods?

There are several DNS switching methods that can be used to change the DNS of devices. The first is manual configuration. Network administrators can define DNS addresses manually through the network settings of devices or routers. This method is suitable for small-scale businesses. Large-scale enterprises typically prefer corporate DNS solutions, and DNS switching is carried out using various management tools. In enterprise DNS management, DNS routing is updated automatically and operates without interruption. Cloud-based DNS management tools also provide centralized control and high scalability. Remember: The right DNS infrastructure ensures secure internet access for employees while protecting your brand’s digital assets against cyber threats.

Best Practices for Secure Access

  • Add an extra layer of protection to DNS by using DNSSEC (Domain Name System Security Extensions) to prevent fraudulent redirections.
  • Protect DNS management with multi-factor authentication.
  • Route all DNS traffic through encrypted protocols (DoH or DoT).
  • Perform regular DNS record audits to remove outdated or incorrect entries.
