ALIAS FOUND
CNAME Target
Shows the destination hostname your subdomain points to through its CNAME record.
Free to use • No registration required
CNAME Lookup Tool
Check CNAME records and verify where a domain or subdomain points.
Understanding Your CNAME Lookup Results
CNAME results show whether one hostname points to another. This is useful for subdomains, SaaS setup, CDN routing, and verification checks.
CONFLICT CHECK
Record Conflicts
A hostname with a CNAME usually should not have other conflicting records on the same name.
BROKEN ROUTE
Invalid or Dead Target
Wrong CNAME targets can break subdomains, third-party integrations, CDN setup, and verification.
About This Tool
What Is a CNAME Lookup?
A CNAME Lookup is a tool that checks the Canonical Name (CNAME) record of a domain or subdomain. A CNAME record creates an alias that points one domain name to another domain name instead of directly to an IP address. This allows multiple subdomains to share the same destination, making DNS management simpler and easier to maintain.
Why Check a CNAME Record?
Checking a CNAME record helps verify that a domain or subdomain is pointing to the correct destination. It is useful when configuring custom domains, connecting third-party services, migrating websites, or troubleshooting DNS issues. Reviewing CNAME records also helps confirm that recent DNS changes have been applied correctly.
What Information Does This Tool Show?
Our CNAME Lookup Tool retrieves the published CNAME record for a domain or subdomain and displays important details, including:Canonical (target) domainAlias hostnameDNS record statusTTL (Time to Live)DNS responseThese details help you verify that your DNS configuration is working as expected.
Who Can Use a CNAME Lookup Tool?
This tool is useful for website owners, developers, system administrators, hosting providers, and IT professionals. Whether you're connecting a custom domain to a website builder, CDN, cloud platform, or another online service, a CNAME lookup helps you verify the DNS configuration quickly.
Best Practices for CNAME Records
Use CNAME records only for aliases and subdomains, not for direct IP addresses. After making DNS changes, allow time for propagation before testing the record. Review your DNS settings whenever you change hosting providers or connect a new service to ensure the CNAME record points to the correct destination.
Why It Matters
1
Verify custom domains
Confirm that a subdomain points to the hostname required by your platform.
2
Avoid broken subdomains
Catch missing or incorrect CNAME records before users see errors.
3
Support CDN and SaaS setup
Validate routing for tools like web apps, documentation, landing pages, and storefronts.
4
Reduce DNS confusion
Understand whether a name resolves directly or through an alias.
How To Improve
1
Enter the exact hostname
Use the full subdomain, such as www.example.com or docs.example.com.
2
Compare the target value
Make sure the CNAME points to the target provided by your host, CDN, or SaaS product.
3
Avoid duplicate record conflicts
Do not combine CNAME with incompatible record types on the same hostname.
4
Recheck after DNS edits
Confirm the updated alias resolves as expected after propagation.
Frequently Asked Questions
A CNAME (Canonical Name) record is a DNS record that points one domain or subdomain to another domain name instead of an IP address. It is commonly used to create aliases for websites and online services.
An A record points directly to an IPv4 address, while a CNAME record points to another domain name. The destination domain is then resolved to its IP address.
In standard DNS, the root domain (such as example.com) generally cannot use a CNAME record because it must support other essential DNS records like NS and MX.
If you've recently added or updated a CNAME record, DNS propagation may still be in progress. It may take some time before the updated record becomes visible across all DNS servers.
Yes, it is technically possible. However, creating multiple CNAME redirects can increase DNS lookup time, so pointing directly to the final destination is generally recommended.
A CNAME record is commonly used when connecting subdomains to services such as website hosting platforms, CDNs, email services, or cloud applications that require a domain alias.
Yes. If a CNAME record points to the wrong destination, the associated subdomain may stop working until the DNS configuration is corrected.
Yes. You can check the CNAME record of any public domain or subdomain online without creating an account.
