00:00:00.000 --> 00:00:06.000
Why does a DNS record point to another name instead of an IP address?

00:00:06.000 --> 00:00:13.000
A CNAME makes one hostname an alias of another hostname.

00:00:13.000 --> 00:00:18.000
Follow the name before the destination.
6 CNAME basics.

00:00:18.000 --> 00:00:30.000
CNAME means canonical name
The record identifies another hostname as the alias target.
Alias hostname · Canonical target · DNS record

00:00:30.000 --> 00:00:42.000
The target is a hostname
A CNAME value is a name rather than a direct IP address.
Target name · Further DNS lookup · Resolved destination

00:00:42.000 --> 00:00:54.000
A service may supply the value
Use the exact hostname specified by the hosting platform.
Provider instructions · Exact target · Correct record name

00:00:54.000 --> 00:01:06.000
An alias is not a redirect
DNS does not by itself change the browser address to another URL.
DNS name resolution · Browser address · Separate HTTP redirect

00:01:06.000 --> 00:01:18.000
Record combinations have limits
Other records at the same name can conflict with a CNAME.
Same record name · Existing records · Provider-specific behaviour

00:01:18.000 --> 00:01:30.000
Test the served website
The destination service must recognise the original hostname too.
Alias resolution · Host configuration · Expected content

00:01:30.000 --> 00:01:39.000
Your checklist
CNAME means canonical name · The target is a hostname · A service may supply the value · An alias is not a redirect · Record combinations have limits · Test the served website

00:01:39.000 --> 00:01:47.000
Check DNS aliasing and website redirects as separate settings.
