2-6 Wired LAN Configurations

Before all computers using wired Ethernet connections (i.e. those
computers that connect to this router's LAN port 1 to 4 by Ethernet
cable) can communicate with each other and access the Internet, they
must have a valid IP address.
There are two ways to assign IP addresses to computers: static IP
address (set the IP address for every computer manually), and dynamic
IP address (IP addresses of computers will be assigned by the router
automatically.
It's recommended for most of computers to obtain an IP address
automatically, as it will save a lot of time on setting IP addresses for
every computer. For servers and network devices which will provide
services to other computers and users that come from Internet, a static
IP address should be used, so other computers can locate the server.
