DNsmasq is a lightweight DNS and DHCP server. It can be used to provide DNS caching and forwarding services, as well as DHCP server functionality. In this tutorial, we will show you how to install DNsmasq on OpenBSD.
Before we begin, make sure you have:
To download DNsmasq, you can visit the official website: dnsmasq/doc.html">http://www.thekelleys.org.uk/dnsmasq/doc.html.
$ ftp http://www.thekelleys.org.uk/dnsmasq/dnsmasq-2.80.tar.gz
After downloading the DNsmasq archive, extract it using the following command:

Now run the following commands to configure, compile and install DNsmasq:
$ ./configure
$ make
$ sudo make install
The installation should now be complete.
To configure DNsmasq, create a new configuration file:
$ sudo vi /usr/local/etc/dnsmasq.conf
In this file, you can specify the DNS and DHCP configuration parameters. For example:
# Listen for queries only on the local interface
interface=lo0
# Forward DNS queries to Google DNS
server=8.8.8.8
# Assign IP addresses to clients on this network
dhcp-range=10.0.0.100,10.0.0.200,12h
Make sure to save the changes made to the configuration file.
To start DNsmasq, run the following command:
$ sudo dnsmasq
If the command runs without any errors, DNsmasq should now be running.
In this tutorial, we have shown you how to install and configure DNsmasq on OpenBSD. DNsmasq is a powerful tool that can be used to provide DNS and DHCP services to your network.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
