Configuring the LAN interface

If you are planning to set up a small home network or connecting your Windows 7 machine to another computer you need to have an IPv4 standard or arrangement. Typically, you may have one computer connected to the Internet which provides Internet services to the other internal computers. Windows 7 can do this role through the Internet Connection Sharing (ICS) service.  Other services or devices such as, Wireless Access Protocol (WAP) in wireless networks or DSL and cable modem routers can too provide Internet services to the internal computers. On the other hand, if you are not planning to provide Internet services then you can avoid all the trouble and let the internal computers configure themselves through APIPA.

Troubleshooting IP Configuration

Windows 7 retains the same command-line tools of its predecessors for troubleshooting IP configurations. The most basic tools are the Ping and Ipconfig utilities which help you determine your system’s IP configuration and test connectivity. There are more advanced network tools such as, Tracert or Pathping, Nslookup for DNS related issues, etc.  These help you troubleshoot advanced network related issues but this article will only cover the basic command-line tools which are adequate for the Windows 7 average users.

IPv4 Configuration in Windows 7

You can view the IP configuration of your computer by using either the command-line tools Ipconfig or Netsh, or by using the Network and Sharing Center. The command-line tools display your computers’ network adapters IP settings including IPv4 and IPv6 addresses, subnet masks and the default gateway.

An IP address identifies a computer in a network and hence, each computer must have a unique address within the same network. Private IP addresses are used for internal networks while public addresses are used for the Internet. Since there are not enough public IP addresses to be allocated for every internal device, we use private addresses internally and use NAT to translate these addresses to a public address. An organization or individual that needs Internet access is allocated one or more public IP addresses through various agencies worldwide that are responsible for the distribution of public IP addresses.

Internet Connection Sharing (ICS)

Sharing the Internet connection over windows 7 requires one computer called the host that is connected to the Internet and to the rest of the computers on the internal network (LAN). Then the computers on the network connect to the Internet via the host computer. The host computer Internet connection can be wireless, modem (Ethernet or USB), 3G card or any similar device. To use ICS make sure that the LAN connection on each computer is configured to get an IP address automatically. This includes the LAN connection of the host computer.
