Not me.

http://www.pool.ntp.org/ redirects me to https://www.ntppool.org/en/.

http://pool.ntp.org/ takes me to an "It works!" default Apache 2 page for an Ubuntu installation. As the comment in the issue describes, http://pool.ntp.org/ takes you to a random ntp server.

If you want another example, try google.com using Google's own DNS:

  PS U:\> nslookup - 8.8.8.8
  Default Server:  google-public-dns-a.google.com
  Address:  8.8.8.8
  
  > google.com
  Server:  google-public-dns-a.google.com
  Address:  8.8.8.8
  
  Non-authoritative answer:
  Name:    google.com
  Addresses:  2607:f8b0:4009:810::200e
            172.217.8.206
  
  > www.google.com
  Server:  google-public-dns-a.google.com
  Address:  8.8.8.8
  
  Non-authoritative answer:
  Name:    forcesafesearch.google.com
  Addresses:  216.239.38.120
            216.239.38.120
  Aliases:  www.google.com

Even if you ultimately end up at the same site through redirects, you're clearly not going to the same site initially.

Either way, the ask was for a difference in www.example.com vs example.com. Not a difference in www.pool.example.com vs pool.example.com. In the latter case, the different subdomains will still be shown (AFAIK).

>Even if you ultimately end up at the same site through redirects, you're clearly not going to the same site initially.

Which is nothing that an end user is going to care about and doesn't provide an example to the asked question.

http://www.pool.example.com displays as http://pool.example.com

For fun I'm going to set up a www.www.www.www.www.www.www.www.www record.

http://www.www.www.www.www.www.www.www.www.www.example.com shows as example.com

E: I'll add it to my certs later but I did it: https://www.www.www.www.www.www.www.www.www.www.www.www.aish...

E2: http://www.example.www.example.org shows up as example.example.org - this is fun.

Re: E2 (http://www.example.www.example.org === example.example.org)

I just found the same thing. How exactly is this a feature? What an insane decision.

[zaarn]

That is absolutely insane and someone should be fired and shamed for this. I didn't like just trimming a pure www. but trimming any www. in the hostname is just dumb behaviour.

How would I differentiate between loadbalancer1.www.intranet and loadbalancer1.intranet? THOSE ARE NOT THE SAME.

Wow. You could do some pretty amazing spoofing with the www.com domain, then.
