IP addresses can be assigned manually or dynamically In most networks, desktop systems (such as Windows Vista) have their systems configured to receive IP addresses (and other TCP/IP configuration information) dynamically through a Dynamic Host Configuration Protocol (DHCP) server Consider Figure 5-6 MCITP1 is configured to get TCP/IP configuration information from DHCP A process commonly referred to as DORA begins when MCITP1 turns on 1 D - Discover The client sends a DHCP discover message This message is simply looking for a DHCP server to offer a lease 2 O - Offer The DHCP server responds with a lease offer A typical lease would include an IP address, a subnet mask, the address of the default gateway, and the IP address of the DNS server 3 R - Request The client responds with a request It s possible for a network to have more than one DHCP server The client will only request the lease from the first DHCP server 4 A - Acknowledge The DHCP server acknowledges the lease request

When it comes to taking tests, knowing what to expect is half the battle The PCAT s Reading Comprehension section assesses a variety of reading skills, from the most basic comprehension skills to the higher-level analysis and evaluation skills Here is a breakdown of skills you should expect to see tested

Routers don t normally pass broadcasts However, DHCP broadcasts are special BOOTP broadcasts that pass through routers on UDP ports 67 and 68 RFC 1542 provides the specifics on this process, and routers that can pass the BOOTP broadcasts are referred to as RFC 1542 compliant In routers on internal networks, DHCP broadcasts are enabled through the router DHCP broadcasts are disabled on routers on the Internet, and boundary routers separating the Internet and intranet For example, consider Figure 5-7 It shows one DHCP server for the headquarters office, but nothing for the remote office separated by the Internet The one DHCP server couldn t provide the remote clients with TCP/IP configuration information over the Internet UDP ports 67 and 68 would be closed on both Router1 and Router2

The clients in the remote office would have to be manually configured Exercise 51 will lead you through the steps to manually configure the clients The DORA process is started by the DHCP Client service You can access the DHCP Client service in the Services applet to verify it is running by clicking Start | Administrative Tools and selecting Services Also any service in the Services applet can be started or stopped using the command line with the Net start and Net stop commands

For example, you can stop and start the DHCP Client service with these commands Since the name of the service (DHCP Client) has a space in it, you need to enclose the entire name in quotes

Net stop "DHCP Client" Net start "DHCP Client"

If something happened to the DHCP server, it wouldn t respond Likewise, if something happened to the router, the DHCP server response wouldn t be heard The result is an Automatic Private IP Address

Automatic Private IP Address (APIPA)

Comprehension These questions look at the author s main idea and support for his or her hypothesis Expect questions on Finding the Main Idea, Locating Supporting Details or Evidence, and Interpreting Vocabulary Comprehension questions make up approximately 30 percent of the Reading Comprehension section of the PCAT

If a client begins the DORA process but never receives a reply from the DHCP server, it will typically assign itself an IP address in the Automatic Private IP Address (APIPA) range APIPA can be disabled, but is usually enabled on clients The APIPA range is

169254yz 25525500 EXAM TIP If you see an APIPA address (anything starting with 169254), you should realize that the DHCP didn t respond Investigate the DHCP server s functionality and the path to and from the DHCP server

Seeing an IP address in the APIPA range lets you know you probably have a problem, though the only thing you know for sure is that the DHCP server couldn t be reached It could be because the DHCP server is down, the router is down, or even that the router is incorrectly configured so that DHCP broadcasts aren t allowed through You may be wondering why APIPA was created It s a valid question The original purpose was to allow computers to be networked together with minimal configuration Consider a small network of five computers If you configured the IP addresses to be assigned automatically but didn t add a DHCP server, all the computers would have APIPA addresses in the 16925400/16 range Since they re all on the same network with the same network ID (16925400), they could all talk to each other A significant drawback today is that APIPA addresses don t have any default gateway This means that APIPA hosts can t get past a router and can t access the Internet
