CNAME Flattening vs HTTP Redirect

CNAME flattening and HTTP redirects solve different problems even though both can affect how users reach a website.

Why it matters

Flattening changes how DNS answers are served, while redirects happen later at the browser or web-server layer.

Use DNS lookup to review whether the hostname is aliased or flattened at the DNS layer.
Use HTTP headers to confirm whether a redirect response is happening at the web layer.
Check A and CNAME behavior together when reviewing apex-domain setups.
Validate SSL behavior if redirects and hostnames are changing during rollout.

Use DNS and HTTP checks together so you do not confuse hostname aliasing with browser redirects.

DNS Lookup Inspect DNS answers, aliases, and flattened behavior. HTTP Headers Confirm whether redirects occur at the application or server layer. SSL Checker Validate hostname and certificate coverage. Website IP Finder Map the destination infrastructure behind the hostname.

CNAME vs HTTP Redirect Compare the two concepts directly. A Record vs CNAME Review hostname aliasing basics. DNS Propagation vs DNS Cache Understand how DNS changes can look inconsistent during rollout.
