HISTORY OF DHCP
4
THE ROLE OF DHCP

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

5
DYNAMIC VERSUS MANUAL TCP/IP ADDRESS ASSIGNMENT
6
Ethernet Address and IP address

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

7
Ethernet Address and IP Address

• Can also view the MAC address by typing
• C\gtipconfig /all
• Start-gtrun-gtmsinfo32 ltentergt

8
IP Addressing Rules and Concepts

• Addresses you cannot assign
• Default route address 0.0.0.0
• Loopback address 127.0.0.1
• Network number 172.17.13.0
• IP Broadcast address 172.17.13.255

9
Dynamic Host Configuration Protocol

• Used for manageability and automation of IP
  address assignment on networks.
• Ie. ISPs use DHCP when you establish
  connection.

10
Scopes and Superscopes

• When configuring DHCP, the first thing you do is
  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 IPs on the same segment.

WHAT IS A DHCP RELAY AGENT?
15
Leases, client options exclusions and reservations

• 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 servers
  IP address and do not want that assigned to
  another machine. What would happen if it did
  assign its 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.

WHAT ARE DHCP CLIENT RESERVATIONS?

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