in a DHCPDISCOVER message and contains the MAC address (hardware address) and the computer name of the DHCP client. 4. The DHCP server that offered the IP address to the client responds to the DHCP DISCOVER message, and the IP address is assigned to the client. If any other DHCP server offered an IP address to the client, it would now withdraw its offer. As you see in Figure 8-6, the assignment of an IP address is not very complicated. However, before an IP address can be issued, you must create a range of IP addresses, called a scope, from which the DHCP Server can choose.

Although a WHILE loop is typically used when implementing a cursor, you can use a WHILE loop to perform operations against one or more rows without a cursor. For example, the following example uses a WHILE loop to increase the list price for products in the AdventureWorks database.

In a hexadecimal number such as 0x0102, the 0x01 is the most significant byte and the 0x02 is the least significant. The left most bytes are more significant because you multiple these digits by a higher power of 16. The right most digits are less significant, and the digits become more significant as you move from right to left. Programs store numbers in memory in two ways: big endian or little endian. When a program stores a number using big endian (big end first) storage, it stores the most significant bytes in memory first, followed by the less significant bytes. When stored in memory using big endian storage, the number 0x01020304 is 0x01 0x02 0x03 0x04. Makes sense, doesn't it The problem is that Intel based processors don't store numbers in memory this way. Intel based processors use the little endian (little end first) architecture, which means they store the least significant bytes first, followed by the more significant bytes. Thus, the number 0x01020304 is 0x04 0x03 0x02 0x01 in memory. Although most of the tools you'll use display all numbers little endian or big endian correctly, you'll have to pay careful attention when you're looking at numbers in binary values because the tools won't automatically reverse the order of the bytes for you. Thus, if you see the number 0x34 0x77 in a binary value, you'll have to remember to reverse the order of bytes to get the result 0x7734.
