10.2 Static IP Addresses

To initiate traffic using utility tools such as ping or iperf, set an IPv4 address. This can be done with a DHCP server to assign dynamic IP addresses or done manually with static IP addresses. When using the static method and a direct connection topology, both link partners need an IP address manually assigned to the same subnet. For example, if the IPv4 address is 192.168.1.1 with a netmask of 24, then the first three set of numbers (that is, 192.168.1.x) is the subnet. Section 11 has an example of how to set static IP addresses at runtime.
