Windows 7 networking starts with the Network and Sharing Center which provides a centralized location where you can view, create, and modify local area network (LAN), wireless local area network (WLAN), virtual private network (VPN), dial-up, and Broadband connections on your client and server computers. In addition, you can configure connections to the local computer and sharing options that specify the content that is available to other computers and devices on the network; and you can use Network and Sharing Center tools like Network Map and Network Location to view and specify additional settings about networks and network profiles. It can also be used to troubleshoot network connectivity issues. The Network and Sharing center can be accessed via the control panel.

If your computer has a network adapter that is connected to a local area network, you do not need to manually create a LAN connection, because Windows automatically creates and configures the connection when you start your computer. Other types of connections such as VPN and dial-up can be configured as follows:

The first time that you connect to a network, you must choose a network location. This automatically sets the appropriate firewall and security settings for the type of network that you connect to. If you connect to networks in different locations (for example, a network at your home, at a local coffee shop, or at work), choosing a network location can help ensure that your computer is always set to an appropriate security level.

• Home Network – For home networks or when you know and trust the people and devices on the network. Computers on a home network can belong to a homegroup. Network discovery is turned on for home networks, which allows you to see other computers and devices on the network and allows other network users to see your computer. For more information, see What is network discovery?

• Work Network – For small office or other workplace networks. Network discovery, which allows you to see other computers and devices on a network and allows other network users to see your computer, is on by default, but you can’t create or join a homegroup.

• Public Network – For networks in public places (such as internet cafes or airports). This location is designed to keep your computer from being visible to other computers around you and to help protect your computer from any malicious software on the Internet. HomeGroup is not available on public networks, and network discovery is turned off. You should also choose this option if you’re connected directly to the Internet without using a router, or if you have a mobile broadband connection.

Once your network connection(s) are established, it is time to configure IP settings. Every IP address can be broken down into 2 parts, the Network ID and the Host ID. All hosts on the same network must have the same netid. Each of these hosts must have a hostid that is unique in relation to the netid. IPv4 addresses are divided into 4 octets with each having a maximum value of 255. We view IPv4 addresses in decimal notation such as 124.35.62.181, but it is actually utilized as binary data.
