macOS 14.3.1: Setting Primary DNS Server with dnsmasq Network
In this article, we will discuss how to set the primary DNS server using the dnsmasq network on macOS 14.3.1. By following this guide, you will be able to configure your Mac to use the primary Cloudflare DNS server through dnsmasq.
What is dnsmasq?
dnsmasq is a lightweight, easy-to-configure DNS forwarder and DHCP server. It is often used in small networks to provide DNS resolution and DHCP services. By using dnsmasq, you can configure custom DNS settings, such as setting the primary DNS server, which can be useful when you want to use specific DNS servers for certain tasks.
Setting up dnsmasq on macOS 14.3.1
To set up dnsmasq on macOS 14.3.1, you will need to install it first. You can install dnsmasq using Homebrew, a package manager for macOS. To install Homebrew, open the Terminal app and paste the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"Once Homebrew is installed, you can install dnsmasq by running the following command:
brew install dnsmasqAfter installing dnsmasq, you need to configure it to use the primary Cloudflare DNS server. To do this, open the dnsmasq configuration file using a text editor, such as nano or vim.
sudo nano /usr/local/etc/dnsmasq.confAdd the following lines to the configuration file:
server=8.8.8.8
server=8.8.4.4These lines tell dnsmasq to use the primary and secondary Cloudflare DNS servers (8.8.8.8 and 8.8.4.4, respectively) for DNS resolution. Save the configuration file and exit the text editor.
Setting the primary DNS server using dnsmasq
Now that you have configured dnsmasq to use the primary Cloudflare DNS server, you need to set it as the primary DNS server for your Mac. To do this, you will need to modify the DHCP client configuration file.
Open the DHCP client configuration file using a text editor:
sudo nano /Library/Preferences/SystemConfiguration/dhcpFind the line that starts with interface en0 and add the following lines below it:
dnsmasq_restart
option domain-name-servers 127.0.0.1
option domain-name "local"These lines tell the DHCP client to use dnsmasq as the DNS server and to use the domain name "local". The dnsmasq_restart option tells the DHCP client to restart dnsmasq when the DHCP lease is renewed. Save the configuration file and exit the text editor.
Finally, you need to restart the DHCP client and dnsmasq to apply the changes. Run the following commands in the Terminal app:
sudo killall -HUP mDNSResponder
sudo brew services restart dnsmasq- dnsmasq is a lightweight, easy-to-configure DNS forwarder and DHCP server.
