How to Edit or Remove a CNAME Record in cPanel on Tublat

Introduction

A CNAME record (Canonical Name record) lets you alias one hostname to another. Over time, you may need to edit a CNAME (change its target) or remove it (if it becomes obsolete or conflicting). If your domain is hosted through Tublat, managing these changes is straightforward via cPanel’s Zone Editor (or DNS Editor). In this guide, you’ll learn step by step how to modify or delete a CNAME, what to watch out for, and how to avoid common DNS errors.

Why You Might Need to Edit or Remove a CNAME

• You changed the target service (e.g. moved from one host to another).

• The alias is no longer needed or you want to repurpose it.

• It conflicts with another DNS record (e.g. A, MX, TXT) for the same name.

• You want to clean up outdated DNS entries.

• You need to adjust TTL or canonical hostname for better performance or alignment with your infrastructure.

DNS misconfiguration can break the alias and make subdomains unreachable, so careful editing or removal is important.

Prerequisites

Before editing or deleting a CNAME record, ensure you have:

1. Access to cPanel and the Zone Editor (DNS management) for the domain.

2. Knowledge of the alias (name) and the current canonical target (hostname) you want to change or remove.

3. Awareness of potential conflicts: you cannot have a CNAME and other record types (A, MX, TXT) for the same name simultaneously.

4. Some time for DNS propagation after changes.

Step-by-Step: How to Edit a CNAME Record in cPanel

1. Log in to cPanel
   Access your cPanel using yourdomain.com/cpanel (or via your Tublat control panel).

2. Open Zone Editor / DNS Management
   In cPanel, go to Domains → Zone Editor or DNS Zone Editor (or similar DNS tool).

3. Choose the domain to edit
   Click Manage (or its equivalent) next to the domain whose CNAME you want to modify.

4. Locate the CNAME record
   Scroll or filter through the DNS records table to find the entry with type CNAME matching the alias you want (for example www, blog, etc.).

5. Click “Edit”
   Next to the CNAME record, click the Edit link or icon. This opens editable fields for that record.

6. Change the target or alias as needed

   • Name / Host: the alias (e.g. www, or subdomain).

   • TTL: optionally adjust the TTL.

   • Target / Canonical name: update the hostname to which the alias should point (e.g. newhost.example.com).

7. Save the record
   Click Save Record, Save, or Update to commit the change. The DNS table updates with the new target.

8. Verify the edit
   Use tools like dig, nslookup, or online DNS checkers to confirm that the alias now resolves to the new canonical name.

Step-by-Step: How to Remove a CNAME Record in cPanel

1. Access DNS / Zone Editor
   Log in to cPanel and navigate to the DNS management or Zone Editor for your domain.

2. Locate the CNAME record you want to delete
   In the domain’s DNS records list, find the CNAME record (alias) that you no longer need.

3. Click “Delete”
   Next to the record, click the Delete link or trash icon. Some interfaces will ask you to confirm deletion — approve it.

4. Commit and verify removal
   The record will disappear from the DNS table. Then use dig or DNS lookup tools to confirm that the alias is no longer resolving to any hostname.

5. Ensure no service interruption
   Before removal, confirm that no service (website, redirect, application) still depends on that alias.

Best Practices & Tips

• Backup DNS settings or take screenshots before editing or deleting.

• Use moderate TTLs (e.g. 3600) during changes so propagation is faster.

• Remove conflicting records first (e.g. an A record with the same name) before adding or editing a CNAME.

• Avoid placing a CNAME at the root domain (apex); most DNS systems don’t allow it.

• After modifications, wait for propagation and clear local DNS cache on your machine.

• If the interface doesn’t show Edit/Delete options, check whether your Tublat plan has DNS editing enabled.

• Always verify the final DNS resolution to confirm changes took effect.

Common Pitfalls & How to Fix Them

• “CNAME and other data” error — appears when trying to add a CNAME where another record type already exists for the same name. You must delete the conflicting record first. support.cpanel.net

• No edit or delete option visible — your hosting plan might restrict DNS management features. Contact Tublat support.

• Changes not showing immediately — due to propagation delay or DNS caching. Wait and retry.

• Broken alias after change — the new target might not have A records or might be incorrect; double-check spelling and configuration.

• Circular alias / loop — avoid pointing a CNAME to another alias that ultimately points back to itself.

Why This Matters for Tublat Users

For Tublat customers, being able to edit or remove CNAME records via cPanel gives you fine control over domain aliasing, subdomains, and integrations with external services. Whether you are switching hosts, updating services, or tidying up DNS, proper CNAME management is essential to avoid broken links or misrouted traffic. This guide ensures you can make safe edits or removals without disrupting your site operations.
