Server Setup

sudo apt install dnsmasq

Edit /etc/dnsmasq.conf:

no-resolv  # for offline / isolated networks only
address=/.apsystemsema.com/192.168.69.100
address=/.apsema.com/192.168.69.100
listen-address=192.168.69.100

Replace 192.168.69.100 with the server's IP address.

Edit router's DHCP DNS settings to use 192.168.69.100 as the name server.
