from an IP address and a network mask
disabled(yes | no; default:no) - specifies whether the address is disabled or not
interface(name) - interface name the IP address is assigned to
netmask(IP address; default:0.0.0.0) - delimits network address part of the IP address from the
host part
network(IP address; default:0.0.0.0) - IP address for the network. For point-to-point links it
should be the address of the remote end

through an interface. They appear automatically, when adding a new IP address. Dynamic
routes are also added by routing protocols.

for static routes may be checked (with either ARP or ICMP protocol) for reachability, so that
different gateways with different priorities (costs) may be assigned for one destination network
to provide failover.
