2-7 Wired LAN Configurations
Before all computers using wired Ethernet connection (i.e. those computers connect 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 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.
