How Does DNS Server Get Updated?

Have you ever wondered how the DNS server gets updated? In this article, we will explore the process of updating DNS servers and understand the importance of keeping them up-to-date.

What is a DNS Server?

A DNS (Domain Name System) server is a crucial component of the internet infrastructure. It translates human-readable domain names, such as, into machine-readable IP addresses. This translation enables your computer to connect to the correct destination on the internet.

Why Update DNS Servers?

Updating DNS servers is essential for several reasons:

  • IP Changes: When a website or service changes its hosting provider or server location, its IP address also changes. Updating the DNS server ensures that visitors can still access the website using its domain name.
  • New Services: Introducing new services or subdomains often requires creating new records on the DNS server.

    These updates enable users to access these new services seamlessly.

  • Maintaining Security: Regularly updating DNS servers helps protect against potential security threats. By keeping up with security patches and updates, administrators can reduce vulnerabilities and safeguard user data.

How Does a DNS Server Get Updated?

The process of updating a DNS server involves multiple steps:

Step 1: Identify Changes

The first step in updating a DNS server is identifying what needs to be changed. This could include adding new records, modifying existing ones, or removing outdated entries.

Step 2: Access Control Panel

To update a DNS server, you need to access your hosting provider’s control panel or domain management interface. This interface allows you to manage your domain’s DNS settings.

Step 3: Locate DNS Management Section

Within the control panel, locate the DNS management section. The specific location may vary depending on your hosting provider, but it is usually found under domain settings or advanced options.

Step 4: Update Records

In the DNS management section, you can add, edit, or remove DNS records. Common types of DNS records include:

  • A (Address) Record: Maps a domain name to an IP address.
  • CNAME (Canonical Name) Record: Creates an alias for a domain or subdomain and points it to another domain’s A record.
  • MX (Mail Exchange) Record: Specifies the mail server responsible for accepting emails for a domain.

To update a record, select the appropriate type and provide the necessary information, such as IP addresses or Target domains. Save the changes once you have completed updating all required records.

Step 5: Propagation

After updating the DNS records, it takes some time for these changes to propagate throughout the internet. This process is known as DNS propagation. During propagation, updated information spreads across different DNS servers worldwide until it reaches every internet service provider (ISP).

Note that propagation can take anywhere from a few minutes to several hours. Until propagation is complete, some users may still see cached old records while others see the updated ones.

The Importance of Patience

When updating a DNS server, it is crucial to exercise patience. Due to propagation delays and caching mechanisms, changes may not take effect immediately for all users. It is advisable to wait for propagation to complete before assuming that the changes are active.

In conclusion, updating DNS servers is essential for maintaining a reliable and secure online presence. By following the necessary steps and understanding the propagation process, you can ensure that your DNS changes are successfully implemented.
