Up to this point, we've been assigning various IPv4 and IPv6 addressing information but
this does not mean that we can browse the internet. For that, we will need to
configure the DNS information; particularly, we need to tell the Linux system which DNS
server to use when attempting to venture out to the internet. As we've seen earlier in this
chapter, there are various text boxes that we can fill out for IPv4, IPv6, gateway and DNS
information using a GUI utility. Here, we will look at configuring the DNS information at
the command prompt; particularly the /etc/resolv.conf file. Here is the content of the
/etc/resolv.conf file:
root@philip-virtual-machine:/home/philip# cat /etc/resolv.conf
# This file is managed by man:systemd-resolved(8). Do not edit.
nameserver 127.0.0.53
root@philip-virtual-machine:/home/philip#
Some output has been omitted for brevity...
