Static IP configuration

As you can see in the VLAN example three interfaces were configured with static IP settings, so these are the commonly used options:

address

the IP address -- required

netmask

the netmask -- required

broadcast

broadcast address -- only required for legacy applications (if using +, it will be calculated automatically by the kernel)

gateway

an IP address added as default gateway if present

mac-address

if you need to change your MAC address (required for some DSL providers)
