canonical name

Why does www.linuxquestions.org resolves to this weird canonical name?
Code:> server 8.8.8.8
Default server: 8.8.8.8
Address: 8.8.8.8#53
> www.linuxquestions.org
Server: 8.8.8.8
Address: 8.8.8.8#53
Non-authoritative answer:
www.linuxquestions.org canonical name = www.linuxquestions.org.cdn.cloudflare.net.
Name: www.linuxquestions.org.cdn.cloudflare.net
Address: 104.24.137.8
Name: www.linuxquestions.org.cdn.cloudflare.net
Address: 172.67.81.99
Name: www.linuxquestions.org.cdn.cloudflare.net
Address: 104.24.136.8
Name: www.linuxquestions.org.cdn.cloudflare.net
Address: 2606:4700:20::ac43:5163
Name: www.linuxquestions.org.cdn.cloudflare.net

Name: www.linuxquestions.org.cdn.cloudflare.net
Address: 2606:4700:20::6818:8908
Never seen such thing on other sites using the [expletives] cloudflare protection. And of course it is inaccessible via the canonical name:
Error 1001

DNS resolution error
What happened?
You've requested a page on a website (www.linuxquestions.org.cdn.cloudflare.net) that is on the Cloudflare network. Cloudflare is currently unable to resolve your requested domain (www.linuxquestions.org.cdn.cloudflare.net). There are two potential causes of this:
Most likely: if the owner just signed up for Cloudflare it can take a few minutes for the website's information to be distributed to our global network.
Less likely: something is wrong with this site's configuration. Usually this happens when accounts have been signed up with a partner organization (e.g., a hosting provider) and the provider's DNS fails.
