How to Set Up DNS in DirectAdmin

Categories: DirectAdmin

Setting up DNS (Domain Name System) in DirectAdmin allows you to connect your domain to your web server, configure email, and direct traffic to the correct location. DNS records manage how your domain name resolves, ensuring visitors can access your website and emails are routed correctly. This step-by-step guide will walk you through setting up and managing DNS in DirectAdmin.

1. Understanding DNS Basics

Before diving into DNS setup, it’s essential to understand the primary types of DNS records and their functions:

• A Record: Points your domain to an IP address, allowing users to access your website.
• CNAME Record: An alias that points one domain to another domain, often used for subdomains.
• MX Record: Directs email for your domain to the correct email server.
• TXT Record: Holds text information, commonly used for domain verification and security (like SPF and DKIM).
• NS Record: Specifies the nameservers for your domain, which direct traffic to the correct DNS configuration.

Tip: Having a basic understanding of these records will make DNS setup easier and help you avoid common configuration errors.

2. Accessing DNS Management in DirectAdmin

To begin setting up DNS for your domain, log in to your DirectAdmin control panel.

• Navigate to DNS Management:
  • Go to Account Manager > DNS Management.
  • Select the domain you want to configure.

The DNS Management page will display a list of your domain’s DNS records, allowing you to add, modify, or delete records as needed.

Tip: If you’re not sure about DNS settings, consult your hosting provider’s documentation or support to avoid unintentional misconfigurations.

3. Setting Up an A Record

The A record is essential as it directs your domain to your server’s IP address. This is typically the first DNS record you’ll set up for a new domain.

• To set up an A record:
  1. In DNS Management, look for the existing A record. If none exists, click Add Record.
  2. In the Name field, leave it blank (this means it will apply to the root domain) or enter a subdomain (e.g., “www” for www.yourdomain.com).
  3. In the Type field, select A.
  4. Enter your server’s IP address in the Value field.
  5. Click Save.

Tip: If you want your domain to resolve with and without “www,” add an A record for both the root domain (blank) and “www” to ensure seamless access.

4. Creating a CNAME Record for Subdomains

CNAME records are commonly used for subdomains, directing them to a primary domain (e.g., “www” to the main domain or “blog” to a separate hosted page).

• To create a CNAME record:
  1. In DNS Management, click Add Record.
  2. Enter the subdomain name in the Name field (e.g., “blog”).
  3. Select CNAME in the Type field.
  4. In the Value field, enter the target domain (e.g., yourdomain.com).
  5. Click Save.

Tip: Only use CNAME records for subdomains. The root domain should always use an A record.

5. Configuring MX Records for Email

MX records specify the email servers for your domain, ensuring email is routed to the correct mail server. You’ll need this record if you want to set up custom email accounts (e.g., [email protected]).

• To set up an MX record:
  1. In DNS Management, click Add Record.
  2. In the Name field, leave it blank if this is for the root domain.
  3. Choose MX in the Type field.
  4. In the Value field, enter the mail server address provided by your email provider (e.g., mail.yourdomain.com).
  5. Set the Priority—lower numbers indicate higher priority (e.g., 10).
  6. Click Save.

Tip: If you use a third-party email service (like Google Workspace or Microsoft 365), consult their documentation for the correct MX record values.

6. Adding TXT Records for Domain Verification and Security

TXT records are often required for verifying domain ownership with external services and improving email security.

• To add a TXT record:
  1. In DNS Management, click Add Record.
  2. Enter the host in the Name field (often “@” or “_domainkey” for DKIM).
  3. Choose TXT in the Type field.
  4. In the Value field, enter the required text, such as an SPF or DKIM record.
  5. Click Save.

Tip: For SPF records, use a format like v=spf1 include:spf.mailprovider.com ~all. Always verify the values with the service you’re integrating with to ensure proper setup.

7. Managing NS Records

NS (nameserver) records point to the authoritative DNS servers for your domain. Typically, your hosting provider supplies these, and you should only change them if you are switching DNS providers.

• To view or edit NS records:
  • Go to the DNS Management section for the domain and look for NS records.
  • Update these if needed, especially if your domain registrar’s or external DNS provider’s nameservers are different from those provided by your hosting provider.

Tip: After updating NS records, it can take up to 48 hours for DNS changes to propagate fully across the internet.

8. Setting Up a PTR Record for Reverse DNS (Optional)

If you’re running email servers or need reverse DNS (rDNS) for other services, you may need a PTR record, which maps an IP address to a domain name.

• PTR records are typically configured by your hosting provider, as they require access to the IP address’s DNS settings. Contact your hosting provider if you need to set up reverse DNS.

Tip: PTR records are crucial for email deliverability, as some email providers may block emails from domains without reverse DNS.

9. Testing and Verifying DNS Settings

After setting up your DNS records, it’s essential to verify that everything is configured correctly. Use online tools like DNS Checker or WhatsMyDNS to check DNS propagation and ensure records are resolving as expected.

• To test DNS records:
  1. Enter your domain into a DNS lookup tool.
  2. Confirm that the records appear correctly across different locations.
  3. For email settings, you can use MX Toolbox to verify MX records and troubleshoot potential issues.

Tip: DNS changes can take up to 24–48 hours to propagate fully, so give it some time before assuming there’s an issue.

10. Troubleshooting Common DNS Issues

If your domain isn’t resolving correctly, or you’re experiencing email or connection issues, consider these common DNS troubleshooting tips:

• Check for Typo Errors: Even a small typo in DNS records can cause issues. Double-check all values, including IP addresses and server names.
• Verify with Your Hosting Provider: Sometimes hosting providers have specific configurations for DNS. Confirm that your settings align with their recommendations.
• Wait for Propagation: DNS changes are not always instant and may take up to 48 hours to propagate globally.
• Clear Cache: Sometimes, DNS issues are due to cached data on your device. Try clearing your browser cache or flushing your local DNS cache.

Tip: If you’re unsure about a DNS issue, your hosting provider’s support team is a valuable resource and can often help diagnose and resolve DNS-related problems.

Setting up DNS in DirectAdmin doesn’t have to be complicated.
