/etc/resolv.conf

/etc/resolv.conf is the resolver configuration file. It's used to access the DNS (domain name service).
The following simple example content specifies the nameserver to be 8.8.8.8: 
nameserver 8.8.8.8
At least in Ubuntu, /etc/resolv.conf is not used anymore, unless its »manually« implemented.
In WSL, /etc/resolv.conf is a symbolic link to a file with the same name under /mnt/wsl.
