3-3-1 Before you start - Suggestions for deciding an IP address to be used
with this broadband router
Before all computers using wired Ethernet connection (i.e. those
computers connect to this router’s LAN port 1 to 4 by Ethernet cable) or
wireless connection can communicate with each other and access 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 address of computers will be assigned by router automatically. It’s
recommended for most of computers to use dynamic IP address, it will
save a lot of time on setting IP addresses for every computer, especially
when there are a lot of computers in your network; for servers and
network devices which will provide services to other computer and users
that come from Internet, static IP address should be used, so other
computes can locate the server.
This broadband router has a built-in DHCP (Dynamic Host Configuration
Protocol) server, and can help you to assign IP addresses to your client
computers. Almost all network computers / devices manufactured after
year 1995 are compatible with DHCP, and you can let this broadband
router to assign the IP address to client computers / devices for you.
