Can't pull anything using docker on Arch
I've installed docker and started the service/daemon for it. But when I try to pull from the registry, it cannot seem to resolve the host:
sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
e6590344b1a5: Retrying in 1 second
docker: error pulling image configuration: download failed after attempts=6: dial tcp: lookup production.cloudflare.docker.com: no such host.I found some topics about modifying the nameserver to 8.8.8.8 or having to use a proxy if you are on vpn or behind a proxy (but I am not using either of those things). The nameserver modification doesn't seem to work.
Anyone else have this problem?

Re: Can't pull anything using docker on Arch
Does DNS resolution work?
drill production.cloudflare.docker.com
ping -4 production.cloudflare.docker.com
ping -6 production.cloudflare.docker.comOffline

Re: Can't pull anything using docker on Arch
Ah, maybe this is a little weird. Drill seems to work fine, but my ping can't seem to resolve hostnames. It's not supposed to be like this, is it?
drill output:

Maybe there's something I messed up in my network config.
Here's /etc/resolv.conf:
# Generated by dhcpcd from enp1s0f0.dhcp, enp1s0f0.ra
# /etc/resolv.conf.head can replace this line
domain hsd1.ca.comcast.net
nameserver 75.75.75.75
nameserver 75.75.76.76
nameserver 2001:558:feed::1
nameserver 2001:558:feed::2
# /etc/resolv.conf.tail can replace this lineAnd /etc/hosts:
# Static table lookup for hostnames.
# See hosts(5) for details.
#
# <ip-address> <hostname.domain.org> <hostname>
127.0.0.1 <redacted> localhost
::1 <redacted> localhost========================
edit: another fact is that I have avahi running on this computer, and systemd-resolved is not. I started systemd-resolved real quick, but ping still did not work.

Nope.

Yep.

That means your Network configuration is managed by dhcpcd? Is this intended?

Please stop "messing around". At best nothing useful happens and the worst case is you damage your installation even further.
What does your "/etc/nsswitch.conf" look like?
