IPv6, cloudflare and related issues

Hi NMGLUG folks,

I heard that using 1.1.1.1 or 1.0.0.1 offers advantages of privacy against
ISPs and occasional faster connections with nameservers to browse the web
more quickly. I heard that this is a service offered by cloudflare and that
I don't need to engage cloudflare to use it. In my Network Connections, I
edited IPv4, adding 1.1.1.1 and 1.0.0.1, and that seems to work well. I
edited IPv6, adding* 2606:4700:4700::1111,2606:4700:4700::1001*
When I test it at https://1.1.1.1/help it's not working right.

I looked at the contents of /etc/resolv.conf It had this:
# Generated by NetworkManager
nameserver 172.16.0.1
nameserver 1.1.1.1
nameserver 1.0.0.1

After rebooting, /etc/resolv.conf  had:
# Generated by NetworkManager
nameserver 172.16.0.1
nameserver 1.1.1.1
nameserver 1.0.0.1
# NOTE: the libc resolver may not support more than 3 nameservers.
# The nameservers listed below may not be recognized.
nameserver 2606:4700:4700::1111
nameserver 2606:4700:4700::1001

This may be a clue why my IPv6 is not working.

I found
https://unix.stackexchange.com/questions/28004/how-to-overcome-libc-resolver-limitation-of-maximum-3-nameservers
This might help, but it has a bunch of stuff in there that I don't follow.

Q
What is the libc resolver?
How can I get IPv6 to work?
Is it a good idea to use this cloudflare service?
Is this cloudflare service considered to be a good thing by the Linux
community?
Is there something better?

On another note, I just published my first book

Thank you to all of you who have helped me with all of my needs.

In gratitude,
LeRoy
