You can manually configure IP addressing if you know your IP address and subnet mask. If you are using optional components such as a default gateway or a DNS server, you will need to know the IP addresses of the computers that host these services as well. This option is not typically used in large networks because it is time consuming and prone to user error. Show
 Each device that will use TCP/IP on your network must have a valid, unique IP address. This address can be manually configured or better yet can be automated through Dynamic Host Configuration Protocol (DHCP). DHCP is implemented as a client-server application. The server is configured with a pool of IP addresses and other IP-related configuration settings, such as subnet mask, default gateway, DNS server address, and WINS server address. The client is configured to automatically request IP configuration information from the DHCP server and use it for a given period of time (the lease length). Dynamic IP configuration assumes that you have a DHCP server on your network that is reachable by the DHCP clients. DHCP servers are configured to automatically provide DHCP clients with all their IP configuration information, including IP address, subnet mask, and DNS server. For large networks, DHCP is the easiest and most reliable way of managing IP configurations. By default, a Windows 7 machine is configured as a DHCP client for dynamic IP configuration. Read more about DNS at: Automatic Private IP Addressing (APIPA) is used to automatically assign private IP addresses for home or small business networks that contain a single subnet, have no DHCP server, and are not using static IP addressing. If APIPA is being used, clients will be able to communicate only with other clients on the same subnet that are also using APIPA. The benefit of using APIPA in small networks is that it is less tedious and has less chance of configuration errors than statically assigning IP addresses and configuration. APIPA is used with Windows 7 under the following conditions:
APIPA uses a Class B network address space that has been reserved for its use. The address space is the 169.254.0.0 network where the range of 169.254.0.1-169.254.255.254 is available for hosts to assign to themselves. Alternate Configuration is designed to be used by laptops and other mobile computers to manage IP configurations when the computer is used in multiple locations and one location requires a static IP address and the other location(s) require dynamic IP addressing. For example, a user with a laptop might need a static IP address to connect to their broadband ISP at home, and then use DHCP when connected to the corporate network. Alternate Configuration works by allowing the user to configure the computer so that it will initially try to connect to a network using DHCP; if the DHCP attempt fails (for example, when the user is at home), the alternate static IP configuration is used. The alternate IP address can be an APIPA or a manually configured IP address.
Although DHCP is the most common method for configuring an IP address on the machines in a network, the other methods are used as well. What is Automatic Private IP Addressing (APIPA)?Automatic Private IP Addressing (APIPA) is a feature of Windows-based OSes -- included since Windows 98 and Windows ME -- that enables a Dynamic Host Configuration Protocol client to automatically assign an IP address to itself when there's no DHCP server available to perform that function. APIPA serves as a DHCP server failover mechanism and makes it easier to configure and support small LANs. DHCP is a network management protocol that organizations can use to dynamically assign IP addresses and other network parameters to devices or nodes on their networks. A DHCP-based service automatically manages client network configurations from a central server, eliminating the need to manually assign IP addresses to the managed devices. DHCP supports networks of all sizes, from those in small organizations to enterprise-scale networks.
When a DHCP client computer connects to the network, it attempts to communicate with a DHCP server. If a server is available, it will assign an IP address and other network parameters to the DHCP client. In some cases, a DHCP server may not be available. For example, the server may be down temporarily or there's no DHCP server on the network. If this occurs and APIPA is enabled, the client computer selects an IP address from a range of predefined addresses -- 169.254.0.0 to 169.254.255.255 -- and automatically assigns that address to itself. The Internet Assigned Numbers Authority (IANA) reserves these addresses specifically for APIPA use cases to ensure they don't conflict with DHCP routable addresses. As part of the APIPA assignment process, the DHCP client uses the Address Resolution Protocol (ARP) to ensure the chosen address isn't being used by another network computer. Once the client has assigned itself an IP address, it can communicate over TCP/IP with other computers on the LAN that are either configured for APIPA or manually set to the correct address range and using a subnet mask of 255.255.0.0.
The APIPA service can be beneficial even if the DCHP client has received a previous IP address from the DHCP server. This is true even if the lease for that address has expired. The user is typically notified when a DHCP client switches between DHCP and APIPA addressing. APIPA is enabled by default, but it can be disabled in some cases, depending on the OS and how the DHCP client is configured.

Which utility would you use to automatically assign IP addresses on a network?Dynamic Host Configuration Protocol (DHCP) is a software utility used to dynamically assign IP addresses to network devices. This dynamic process eliminates the need to manually assign IP addresses. A DHCP server can be set up and the hosts can be configured to automatically obtain an IP address.
Which utilities would you use to find the path between two computers?Tracert. Tracert, also known as traceroute, is another basic networking utility. You can access it through the command line on most operating systems. Tracert is useful in a similar way to ping, in that it looks at the connection between the sender and the destination.
What is the biggest benefit to using a DHCP server in a large network?One of the main benefits of using a DHCP server compared to other networking solutions is that it's a lot faster to set up a TCP/IP network. Additionally, it's much easier to manage such a network because there's no heavy lifting - the server automatically assigns IP addresses so IT staff don't have to.
