Designing a Network and Routing Solution
This subsection covers a summary of highlights from the “Designing a Network
and Routing Solution” section in the Exam 70-297 Study Guide.
IP address assignment
• IP addresses configured manually are known as static IP addresses.
• Automatic IP address assignment works on DHCP clients that do not find a
DHCP server on startup.
• The APIPA IP address range is 169.254.0.0 to 169.254.255.254.
• Clients configured with APIPA poll for a DHCP server every five minutes.
• APIPA clients cannot connect to the Internet.
• Alternate IP addressing is used in place of APIPA.
• Alternate IP addressing is usually configured on portable computers.
Automatic IP addressing with DHCP
• DHCP severs are used to automatically assign IP addresses to clients.
• The DHCP server must be authorized in Active Directory to serve clients.
• A DHCP client sends out a DHCP Discover broadcast message on the network.
• The DHCP server with a valid IP address scope offers an IP address lease to
• The DHCP client accepts the lease offer and requests the IP address from the
• The DHCP server that sent the IP lease offer to the DHCP client assigns the
IP address to the client for a period that is specified in the lease.
• The default lease is for eight days.
• Every DHCP server has at least one active scope.
• The scope contains the following configuration for the clients:
— The range of IP addresses for clients.
— The subnet mask for the network segment.
— The period of the lease, which is eight days, by default.
— DHCP scope options that include the addresses of the default gateway,
the DNS server, and the WINS server.
— The exclusions range that specifies the IP addresses not to be assigned by
the DHCP server.
— The reserved IP addresses for clients who should get the same IP
addresses every time.
