D-Link DSL-G624T Router User Manual


 
DSL-G624T Wireless A DSL Router User’s Guide
(each computer must have a unique address to distinguish it on the network). The IP address scheme used in Example
#1 can be used for any LAN that requires up to 253 separate IP addresses (excluding the Router). Notice that the subnet
mask is the same for all machines and the default gateway address is the LAN IP address of the Router.
It is a good idea to make a note of each device’s IP address for reference during troubleshooting or when adding new
stations or devices.
Using DHCP
The second way to use the default settings is to allow the Router to automatically assign IP settings for workstation
using DHCP. To do this, simply make sure your computers’ IP addresses are set to 0.0.0.0 (under Windows, choose the
option Obtain an IP address automatically in the TCP/IP network component described above). When the computers are
restarted, their IP settings will automatically be assigned by the Router. The Router is set by default to use DHCP. See
the discussion in Chapter 3 for information on how to use configure the Router for DHCP.
Changing the IP Address of the Router
When planning your LAN IP address setup, you may use any scheme allowed by rules that govern IP assignment. It
may be more convenient or easier to remember an IP scheme that use a different address for the Router. Or you may be
installing the Router on a network that has already established the IP settings. Changing the IP address is a simple
matter and can be done using the web manager (see LAN IP Address in Chapter 5). If you are incorporating the Router
into a LAN with an existing IP structure, be sure to disable the DHCP function. Also, consider the effects of NAT
(Network Address Translation). This is enabled by default but may be disabled in the NAT menu of the Advanced
directory.
An IP addressing scheme commonly used for Ethernet LANs establishes 10.0.0.1 as the base address for the network.
Using Example #2 below, the Router is assigned the base address 10.0.0.1 and the remaining addresses are assigned
manually or using DHCP.
Alternative IP Assignment
Host IP Address Subnet Mask Gateway IP
Router
10.0.0.1 255.0.0.0
Computer #1
10.0.0.2 255.0.0.0 10.0.0.1
Computer #2
10.0.0.3 255.0.0.0 10.0.0.1
Computer #3
10.0.0.4 255.0.0.0 10.0.0.1
IP Setup - Example #2
These two examples are only examples you can use to help you get started. Other common private network IP
addressing schemes use a base address of 192.168.0.1 or 10.1.1.1. If you are interested in more advanced information
on how to use IP addressing on a LAN there are numerous resources freely available on the Internet. There are also
many books and chapters of books on the subject of IP address assignment, IP networking and the TCP/IP protocol
suite.
