2-6 Wired LAN Configurations
Before all computers using wired Ethernet connection (i.e. those computers
connected to this router’s LAN port 1 to 4 by Ethernet cable) 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 that other computes can
locate the server.
Suggestions on IP address numbering plan:
If you have no idea on how to define an IP address plan for your network, here are
some suggestions.
1.
A valid IP address has 4 fields: a.b.c.d, for most of home and company
users, it’s suggested to use 192.168.c.d, where c is an integer between 0
and 254, and d is an integer between 1 and 254. This router is capable to
work with up to 253 clients, so you can set ‘d’ field of IP address of router
as 1 or 254 (or any number between 1 and 254), and pick a number
between 0 and 254 for field ‘c’.
2. In most cases, you should use ‘255.255.255.0’ as subnet mask, which
allows up to 253 clients (this also meets router’s capability of working with
up to 253 clients).
3.
For all servers and network devices which will provide services to other
people (like Internet service, print service, and file service), they should
use static IP address. Give each of them a unique number between 1 and
253, and maintain a list, so everyone can locate those servers easily.
4. For computers which are not dedicated to provide specific service to
others, they should use dynamic IP address.
If you don’t really understand the descriptions listed above, don’t worry! We
will provide recommended setup values below.
