DNS (Domain Name System) conflicts between your hosting provider and domain registrar can cause significant issues for your website and email services. When DNS settings are misconfigured or conflicting between your registrar and hosting provider, it can lead to downtime, poor email deliverability, and other connectivity issues. Understanding how to resolve these conflicts is essential for maintaining your website’s functionality and ensuring reliable service for your users.

This article provides a detailed guide on identifying and resolving DNS conflicts between your hosting provider and domain registrar. It covers everything from common causes of DNS conflicts, troubleshooting steps, and best practices to avoid future issues.

What Are DNS Conflicts?

A DNS conflict occurs when multiple DNS records or configurations conflict with each other, causing errors in name resolution. These conflicts typically arise between the DNS settings configured by the domain registrar (where your domain is registered) and the DNS settings configured by your web hosting provider (where your website is hosted). When these two configurations do not align, the DNS lookup fails, leading to issues like website downtime, non-functioning email, or redirect problems.

Common DNS Conflicts Between Hosting and Registrar

• Nameserver Misconfigurations: If the nameservers at your registrar are pointing to a different set of nameservers than those used by your hosting provider, the DNS lookup will fail.
• DNS Record Conflicts: Different DNS records for the same domain (e.g., A records or MX records) set by the hosting provider and registrar can lead to DNS resolution issues.
• Propagation Delays: DNS changes made at either the hosting or registrar level may take time to propagate across the global network, which can temporarily cause discrepancies in DNS resolution.
• Overwritten Records: When your registrar updates DNS records or your hosting provider makes changes to them, it can lead to overwriting or incorrect configurations, causing conflicts.

Identifying DNS Conflicts

Before resolving DNS conflicts, it's essential to identify the root cause of the issue. Here are some steps you can take to identify DNS conflicts:

Check Nameservers

Start by comparing the nameservers set at your domain registrar and those configured at your hosting provider. If they don’t match, this could be the cause of your DNS issues.

• Registrar: Login to your domain registrar account and check the nameservers associated with your domain.
• Hosting: Check with your hosting provider to see what nameservers they recommend. You can typically find this information in your hosting control panel or by contacting customer support.

Review DNS Records

Examine the DNS records (A, CNAME, MX, TXT, etc.) configured at both the registrar and hosting provider. Conflicting records can cause issues.

• Registrar DNS Records: Access your domain’s DNS management panel at your registrar and review the DNS records.
• Hosting DNS Records: If you manage your DNS settings through your hosting control panel (e.g., cPanel), review the DNS records configured there as well.

Test DNS Propagation

Changes to DNS records take time to propagate across the global network. Use DNS lookup tools to check if the correct DNS records are being served.

• DNS Lookup Tools: Tools like What’s My DNS, MXToolbox, or DNSstuff can help check the current DNS records and ensure they match across different regions.

Confirm Domain Resolution

You can also confirm if your domain resolves correctly to your website and email services by checking the following:

• Website Access: Visit your domain in a browser and check if it loads the correct website.
• Email Functionality: Check if your email service is working correctly by sending and receiving test emails.

Common Causes of DNS Conflicts Between Hosting & Registrar

Nameserver Configuration Errors

The most common DNS conflict arises when nameservers at the registrar are pointing to different servers than those used by the hosting provider. For example, if your registrar has nameservers pointing to your hosting provider’s default nameservers, but your hosting provider requires custom nameservers, DNS lookups may fail.

Solution: Ensure that the nameservers at your registrar match the nameservers provided by your hosting provider. This is usually done through your registrar’s DNS management dashboard.

Multiple DNS Providers

If you have multiple DNS providers—such as using your registrar’s default DNS service while hosting with another provider—it can lead to DNS conflicts when records don’t sync across both providers.

Solution: It’s best to use one DNS provider for all records. If your hosting provider offers DNS management, switch to using their DNS service exclusively. Update your nameservers at the registrar to point to your hosting provider’s DNS servers.

Incorrect or Overwritten DNS Records

If you made DNS changes at your registrar and your hosting provider also updated records, you might find that one set of DNS records overwrites the other. For instance, your hosting provider may configure a new A record that conflicts with a previously configured CNAME or A record at your registrar.

Solution: Check and manually update DNS records at both the registrar and hosting provider. Make sure records do not conflict and that only one set of authoritative DNS records is used.

DNS Propagation Delays

When DNS records are updated, changes can take time to propagate across the internet. This can cause temporary conflicts, where your domain may still be resolving to the old DNS records.

Solution: Wait for full propagation to complete (up to 48 hours). Use DNS propagation checker tools to monitor the process.

Caching Issues

Local DNS caches or browser caches might show outdated DNS records, causing issues when attempting to access your website or email services.

Solution: Clear your browser cache and local DNS cache (e.g., by running ipconfig /flushdns on Windows). You can also ask users to clear their DNS cache or wait for it to expire.

How to Resolve DNS Conflicts Between Hosting and Registrar

Verify and Sync Nameservers

Start by ensuring that the nameservers at your domain registrar point to your hosting provider's nameservers. This can typically be done from the domain management panel at your registrar.

1. Login to Registrar: Log into your domain registrar's account (e.g., GoDaddy, Namecheap, etc.).
2. Find Nameserver Settings: Locate the DNS or Nameserver settings in your domain dashboard.
3. Update Nameservers: Replace any existing nameservers with the ones provided by your hosting provider. These are usually found in your hosting control panel (e.g., cPanel).
4. Save Changes: Confirm and save the updated nameserver settings.
5. Allow for Propagation: Wait for DNS propagation to complete (up to 48 hours).

Ensure No Conflicting DNS Records

Check both your registrar’s DNS settings and your hosting provider’s DNS settings to ensure no conflicting records exist.

1. Access DNS Settings at Registrar: Go to your registrar’s DNS management panel and review the records (A, CNAME, MX, etc.).
2. Access DNS Settings at Hosting: If you are using a hosting provider's DNS service, log in to the hosting control panel and review the DNS records.
3. Ensure Records Don’t Conflict: Ensure there are no conflicting records between your registrar and hosting provider. Common conflicts include duplicate A records, conflicting MX records, or CNAME and A record mismatches.
4. Update Records: If needed, update the DNS records at either the registrar or hosting provider to ensure consistency.

Choose One DNS Provider

It’s best to use either your hosting provider or your registrar as the primary DNS provider. If your hosting provider offers DNS management, it is usually best to use their DNS service and configure the nameservers at your registrar to point to your hosting provider.

1. Switch to Hosting DNS: If you decide to use your hosting provider’s DNS management, log in to your registrar’s account and update the nameservers to point to your hosting provider’s nameservers.
2. Use Registrar’s DNS: If you prefer to manage DNS through your registrar, update the records at the registrar’s control panel to match your hosting provider’s recommended settings.

Troubleshoot DNS Propagation

Once changes are made, it’s important to check whether DNS propagation has occurred properly. You can use online tools to check if your changes have propagated across the globe.

• Tools to Check Propagation:
  • What’s My DNS: Check your DNS records globally.
  • MXToolbox: Check the status of DNS records, including A, MX, and other essential records.
  • DNSstuff: Use DNSstuff to monitor DNS propagation and resolve issues.

Clear Caches

If you are still encountering issues after the DNS changes have propagated, clear your local DNS cache and browser cache to ensure you are accessing the most current DNS records.

1. Clear Browser Cache: This can be done in your browser’s settings.
2. Flush DNS Cache on Computer:
   • Windows: Run ipconfig /flushdns in the Command Prompt.
   • MacOS: Run sudo killall -HUP mDNSResponder in the Terminal.

Best Practices to Prevent Future DNS Conflicts

Keep DNS Management Centralized

To avoid conflicts, it’s best to keep your DNS management centralized. Use either your hosting provider’s DNS service or your domain registrar’s DNS service, but not both. This helps to maintain consistency in your DNS records.

Document DNS Changes

When making DNS changes, document them carefully. This way,

you can track what changes were made and when, making it easier to troubleshoot any issues later.

Regularly Monitor DNS Health

Use DNS monitoring tools to check the health of your DNS records regularly. Tools like MXToolbox and DNSstuff can help ensure your DNS records are functioning properly.

Keep Records Updated

When adding new services (e.g., email services or content delivery networks), ensure that all relevant DNS records are updated accordingly and don’t conflict with existing settings.
