Using Dhcp, Changing the IP Address of the Modem

DSL-360T ADSL Modem User’s Guide

network IP address (all machines must belong to the same IP network), while the last number denotes the host IP address (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 Modem). Notice that the subnet mask is the same for all machines and the default gateway address is the LAN IP address of the Modem.

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 Modem 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 Modem. The Modem is set by default to use DHCP. See the discussion in Chapter 5 for information on how to use configure the Modem for DHCP.

Changing the IP Address of the Modem

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 Modem. Or you may be installing the Modem 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 Modem into a LAN with an existing IP structure, be sure to disable the DHCP function. Also, consider the effects of the NAT function which is enable by default.

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 Modem 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
Modem	10.0.0.1	255.255.255.0
Computer #1	10.0.0.2	255.255.255.0	192.168.1.1
Computer #2	10.0.0.3	255.255.255.0	192.168.1.1
Computer #3	10.0.0.4	255.255.255.0	192.168.1.1

IP Setup - Example #2

These two examples are only examples you can use to help you get started. 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.

DSL-360T specifications

The D-Link DSL-360T is a versatile ADSL modem/router designed to cater to the needs of home and small office users. This device integrates the functionalities of both a DSL modem and a router, allowing users to connect their devices to the Internet wirelessly or through wired connections.

One of the main features of the DSL-360T is its support for ADSL2/2+ technology, which enhances Internet connectivity by offering higher speeds compared to standard ADSL. This modem can achieve downstream data rates of up to 24 Mbps, making it suitable for streaming, online gaming, and other bandwidth-intensive tasks. Such capability ensures that users can enjoy smooth and reliable Internet access, even with multiple devices connected simultaneously.

The DSL-360T also features built-in NAT (Network Address Translation) and DHCP (Dynamic Host Configuration Protocol), which simplifies network management and allows multiple devices to share a single Internet connection. This feature is particularly advantageous for small offices or households with several users, as it eliminates the need for additional hardware to manage the network.

In terms of connectivity, the device is equipped with four Ethernet LAN ports, allowing for wired connections to computers, printers, and other devices. This wired option offers a stable and high-speed connection, ideal for tasks such as large file transfers or video conferencing. The router also has wireless capabilities, supporting the 802.11g standard for Wi-Fi connections, providing users with the flexibility to access the Internet from anywhere within the range of the network.

Security is another important aspect of the DSL-360T, which comes with built-in firewall protection and support for WPA/WPA2 encryption protocols. These features ensure that users’ data remains secure from unauthorized access, a critical consideration in today’s digital age.

The compact design of the modem/router is user-friendly, with LED indicators that provide real-time information about the device’s status, including power, DSL, and LAN connectivity. This visual feedback helps users troubleshoot any potential issues quickly.

In conclusion, the D-Link DSL-360T is a robust solution for users seeking reliable ADSL connectivity combined with versatile networking capabilities. With its support for advanced ADSL technologies, multiple connection options, and strong security measures, this device is well-suited for both home and small office environments.
