The CNAME record of www.github.com: the name it is an alias of (github.com.).

Example 6 of 13 in **Record Types** · [DNS Lookup Examples](/reference/lookup/dns/examples/) · endpoint: [DNS](/reference/lookup/dns/)

Tags: `param` `domain` · `param` `type` · `value` `www.github.com` · `value` `CNAME`

Asks for the `CNAME` record of `www.github.com`.

A `CNAME` makes one name an alias of another. The answer is a single record: `www.github.com` is an alias of `github.com.` (with the trailing dot of a fully qualified name).
