Docker containers using Google DNS?

I've noticed these recurring log entries showing up on our Docker runners:

level=info msg="No non-localhost DNS nameservers are left in resolv.conf. Using default external servers: [nameserver 8.8.8.8 nameserver 8.8.4.4]"
level=info msg="IPv6 enabled; Adding default IPv6 external servers: [nameserver 2001:4860:4860::8888 nameserver 2001:4860:4860::8844]"

I'm wondering if we should instead ensure the containers are using the same DNS as the hosts?

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
