Frequently asked questions

What does a CNAME record do?

A CNAME record points one hostname to another hostname instead of directly to an IP address.

Is this CNAME lookup free to use?

Yes. It works online in the browser.

When should I use CNAME Lookup instead of A Record Lookup?

Use CNAME lookup when you want to see whether a hostname aliases to another hostname. Use an A-record check when you want direct IPv4 address mapping.

Common issues people run into

The user queries the root domain and expects a CNAME where it may not be allowed.

Fix: Check whether the specific DNS provider or host supports CNAME at that level.

The user expects an IP address instead of an alias target.

Fix: Use A or AAAA lookup if you want direct address records.

No CNAME result appears because the host uses another record type.

Fix: Check the host with a broader DNS tool if you are unsure which record type is configured.
