When you install a new project, you often need to edit your
/etc/hosts file. It isn’t really painful but wouldn’t it be better if we could avoid it?
I have used Dnsmasq for a decade to solve these kinds of problems, and I’m really happy with it. I asked around me, and it does not seem to be widely used! In this blog post I want to show you how simple it is to install and setup so you never have to edit your
/etc/hosts by hand 😀

From its documentation:
Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot. It is designed to be lightweight and have a small footprint
With Dnsmasq, you’ll be able to resolve any TLD to a specific IP address. For example, all the following domain names will resolve to 127.0.0.1:

On Ubuntu based distribution, you’ll need to run:
sudo apt update
sudo apt install dnsmasq
Now, to resolve all
test TLD to 127.0.0.1:
echo 'address=/test/127.0.0.1' | sudo tee /etc/dnsmasq.d/test
Since we changed the configuration, we need to restart the daemon
systemctl restart dnsmasq
On some distributions, systemd adds a custom resolver. So you’ll need to disable it.
DNSStubListener=no' | sudo tee /etc/systemd/resolved.conf
systemctl restart systemd-resolved
And that’s it! Ubuntu takes care of adding Dnsmasq server to the
/etc/resolv.conf file for you!
Now, you’ll never have to edit your
/etc/hosts file anymore!
By the way, did you know we already talked about PHP, DNS, and DNSmasq 🥖?
