NT1330 Client-Sever Networking II 09/23/2014 DNS servers provide domain name resolution for network resources. They associate the TCP/IP address assigned by DHCP to a client with its fully qualified domain name. The association of an IP address to a domain domain name requires that a change in either the address or the name requires an update of the information in DNS. The DHCP protocol does not do this automatically. To make this more seamless, servers running Windows Server® 2008 and DHCP and clients running DHCP can register with DNS, allowing the two to co-operate. Dynamic Host Configuration Protocol (DHCP) is a protocol that assists in configuring IP addresses, subnet masks, default routers, and other IP parameters to client PCs that don't have a static IP address. These computers locate a DHCP server in their local network that gives them an IP address so they can connect to the internet or other computers within the local network. There are four way to allocate dynamic IP addresses: automatic, dynamic, roaming, and manual. Three of these (dynamic, roaming, and manual) use DHCP to assign the IP addresses. There are a number of downsides to administering IP addresses statically. Foremost is human error. If the administrator mistypes the IP address or subnet mask, the workstation may not have connectivity to the resources it requires. If the DNS or WINS server IP addresses are mistyped, the workstation will not be able to perform name resolution. If the default gateway gateway is incorrect, the workstation will not be able to connect to remote subnets and resources. All of the aforementioned problems of statically maintaining IP addresses lend credence to the argument of using a DHCP server regardless of the number of hosts that are supported on the LAN.

NT1330 Client-Sever Networking II 09/23/2014 In my opinion, it would be preferable to use DHCP for all client devices and maintain static IP addresses for all network devices, regardless of the size of the network. Client devices include: Desktops, Laptops, Tablets and other mobile devices. Network devices include: Servers, Printers, Routers, Switches, etc. This would ensure that users can actively gain an IP address, in any location, especially in areas where laptop users roam around, to do what they need to do. Obviously, you have to design and manage your scopes well to ensure that you do not run out of IP addresses. But again this all comes down down to designing your network correctly to ensure that static devices have their own IP range, and the client devices have their own IP range appropriate to the size of the organization and projected growth.
