How to Create a DNS (Converting IP Address to Sub Domain)

Creating a DNS record to associate a subdomain with an IP address involves configuring the Domain Name System (DNS) settings for your domain. The steps can vary slightly depending on your domain registrar or DNS hosting provider. Here is a general guide:

1. Log in to Your Domain Registrar or DNS Hosting Provider:

• Access the account where you manage your domain’s DNS settings. This is typically your domain registrar (where you purchased the domain) or a DNS hosting provider.

2. Locate DNS Management or DNS Settings:

• Find the section in your account dashboard related to DNS management or DNS settings.

3. Choose Your Domain:

• If you have multiple domains, select the one for which you want to create the subdomain.

4. Add a DNS Record:

• Look for an option to add a new DNS record. This might be labeled as “Add Record,” “Add DNS,” or something similar.

5. Select Record Type:

• Choose the type of DNS record you want to create. In this case, you’ll likely choose an “A Record” (IPv4 address) or a “CNAME Record” (Canonical Name, used for aliasing one domain to another).

6. Configure the Record:

• Depending on the record type:
  • For A Record:
    • Enter the subdomain in the “Name” or “Host” field.
    • Enter the IP address in the “Points to” or “Address” field.
  • For CNAME Record:
    • Enter the subdomain in the “Name” or “Alias” field.
    • Enter the domain or hostname (not the IP address) that the subdomain should point to in the “Points to” or “Canonical name” field.

7. Save Changes:

• After configuring the record, save the changes. This might involve clicking a “Save” or “Submit” button.

8. Propagation Time:

• DNS changes can take some time to propagate across the internet. This process may take from a few minutes to 48 hours. During this period, users might see the old information until the changes are fully propagated.

Example:

• Suppose you want to create a subdomain “blog” that points to the IP address “192.168.1.100.” You might create an A Record like this:
  • Name/Host: blog
  • Points to/Address: 192.168.1.100

9. Verify Configuration:

• After propagation time has passed, you can verify your configuration by attempting to access the subdomain in a web browser.

Important Notes:

• DNS changes impact everyone accessing your domain, so make changes cautiously.
• Always use the official interface provided by your domain registrar or DNS hosting provider.
• If you’re unsure about the process, consult your provider’s documentation or support.

Remember that DNS settings may look different based on the provider. If you encounter difficulties, refer to your provider’s support resources or contact their support for assistance.
