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
The CNAME Lookup Tool checks whether a domain or subdomain is using a canonical name record. CNAME records are commonly used to point subdomains such as blog, app, shop, or docs to another hostname.
Use it to verify third-party service setup, CDN connections, SaaS custom domains, and subdomain routing.
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
It points an alias hostname to another canonical hostname instead of directly pointing to an IP address.
Traditional DNS rules restrict CNAME at the root, although some providers offer flattening or ALIAS-style behavior.
Long CNAME chains can add extra DNS lookups. Pointing directly to the required target is usually cleaner.
The record may be missing, cached, not propagated, or blocked by another record on the same hostname.
