What is a CNAME record?

A DNS record that maps one name to another canonical name.

Updated: October 9, 2026

A CNAME record makes one DNS name an alias of another canonical name. It is often used to point a service name at a CDN-managed name.

Reading the result

Enter the alias hostname in DNS Lookup, select CNAME, complete verification, and search.

NetKarte shows the queried name and CNAME target. The target's A or AAAA records determine the eventual IP address.

Limitations

A CNAME owner name generally cannot contain other ordinary data. Long alias chains can add latency and failure points.

Follow an alias

In the illustrative www.example.com → edge.example.net, the left name is the alias and the right is its target. Query the target's A/AAAA in DNS Lookup to inspect published IPs. This is not an HTTP redirect to a different page URL.

No CNAME may simply mean A is configured directly. Conversely, an alias is not useful if its target cannot resolve. NetKarte does not provide a complex chain graph or loop diagnosis. Check your DNS provider's rules before changing records at the same name.
