A.5.2 Configuring DNSMASQ with multiple subnets
Example 14 demonstrates the modifications to the /etc/dnsmasq.conf configuration file that
are required to support multiple subnets, integrated into the operation of Insight Control for Linux's
requirements. In the example, two additional subnets, 172.1.2.0/24 and 172.1.3.0/24, are
configured. Each subnet must be provided with its own routers and IP address ranges that are
specific to it.
