MAC Address IP Addressing DHCP Client DHCP Server Scope Exclusion Range Reservations Netsh

Dynamically assigns TCP/IP addresses Dynamically assigns TCP/IP configuration information Simplifies network administration

Each machine has an Ethernet address and IP address – Ethernet is a unique 48 bit address Also known as MAC (media access control) addresses

Can also view the MAC address by typing: – C:\>ipconfig /all – Start->run->msinfo32

Addresses you cannot assign – Default route address: – Loopback address: – Network number: – IP Broadcast address:

Used for manageability and automation of IP address assignment on networks. – Ie. ISP’s use DHCP when you establish connection.

When configuring DHCP, the first step is to create a range of addresses that will be managed. This is called a scope. A single DHCP server can service more than one subnet by assigning a scope to each subnet. You can create a superscope to service more than on range of IP’s on the same segment.

A lease determines how long the client will maintain the same IP address before it is issued a new lease of another IP address Client options are configured during the setup or after. They can range from simply setting the default gateway, DNS and WINS servers to Network Time Servers and NetBios Settings Exclusions are IP Addresses within the scope that you do not want assigned dynamically. For instance you may statically assign your server’s IP address and do not want that assigned to another machine. What would happen if it did assign it’s own IP address? – A single exclusion can be created or a range of exclusions Reservations ensure that the same MAC gets the same ip address every time. Reservations are created within the scope.

Client reservations permanently reserve a specific address for a specific client.
