2 19-1 IPv4 ADDRESSES An IPv4 address is a 32-bit address that uniquely and universally defines the connection of a device (for example, a computer or a router) to the Internet. Topics discussed in this section: Address Space Notations Classful Addressing Classless Addressing Network Address Translation (NAT) 19.2

3 19.3 The network layer is responsible for the source-to-destination delivery of a packet, possibly across multiple networks (links). Whereas the data link layer oversees the delivery of the packet between two systems on the same network (links), the network layer ensures that each packet gets from its point of origin to its final destination. The network layer adds a header that includes the logical addresses of the sender and receiver to the packet corning from the upper layer. If a packet travels through the Internet, we need this addressing system to help distinguish the source and destination. When independent networks or links are connected together to create an internetwork, routers or switches route packets to their final destination. One of the functions of the network layer is to provide a routing mechanism.

5 Note An IPv4 address is 32 bits long. 19.5

6 Note The IPv4 addresses are unique and universal. 19.6

7 Note The address space of IPv4 is 2 32 or 4,294,967,

8 Figure 19.1 Dotted-decimal notation and binary notation for an IPv4 address 19.8

9 Example 19.1 Change the following IPv4 addresses from binary notation to dotted-decimal notation. Solution We replace each group of 8 bits with its equivalent decimal number (see Appendix B) and add dots for separation. 19.9

10 Example 19.2 Change the following IPv4 addresses from dotted-decimal notation to binary notation. Solution We replace each decimal number with its binary equivalent (see Appendix B)

11 Example 19.3 Find the error, if any, in the following IPv4 addresses. Solution a. There must be no leading zero (045). b. There can be no more than four numbers. c. Each number needs to be less than or equal to 255. d. A mixture of binary notation and dotted-decimal notation is not allowed

12 Classful Addressing IPv4 addressing, at its inception, used the concept of classes. This architecture is called classful addressing. Although this scheme is becoming obsolete, we briefly discuss it here to show the rationale behind classless addressing. Note In classful addressing, the address space is divided into five classes: A, B, C, D, and E

13 19.13 Figure 19.2 Finding the classes in binary and dotted-decimal notation

14 Figure 24-5 Internet Classes McGraw-Hill The McGraw-Hill Companies, Inc., 2001

15 Example 19.4 Find the class of each address. a b c d Solution a. The first bit is 0. This is a class A address. b. The first 2 bits are 1; the third bit is 0. This is a class C address. c. The first byte is 14; the class is A. d. The first byte is 252; the class is E

16 Table 19.1 Number of blocks and block size in classful IPv4 addressing Netid and Hostid In classful addressing, an IP address in class A, B, or C is divided into netid and hostid. These parts are of varying lengths, depending on the class of the address. Figure 19.2 shows some netid and hostid bytes. The netid is in color, the hostid is in white. Note that the concept does not apply to classes D and E. In class A, one byte defines the netid and three bytes define the hostid. In class B, two bytes define the netid and two bytes define the hostid. In class C, three bytes define the netid and one byte defines the hostid

17 Note In classful addressing, a large part of the available addresses were wasted

19 Figure 24-7 Class Ranges of Internet Addresses McGraw-Hill The McGraw-Hill Companies, Inc., 2001

20 Note Classful addressing, which is almost obsolete, is replaced with classless addressing

22 Example 19.5 Figure 19.3 shows a block of addresses, in both binary and dotted-decimal notation, granted to a small business that needs 16 addresses. We can see that the restrictions are applied to this block. The addresses are contiguous. The number of addresses is a power of 2 (16 = 2 4 ), and the first address is divisible by 16. The first address, when converted to a decimal number, is 3,440,387,360, which when divided by 16 results in 215,024,

23 19.23 Figure 19.3 A block of 16 addresses granted to a small organization

24 Note In IPv4 addressing, a block of addresses can be defined as x.y.z.t /n in which x.y.z.t defines one of the addresses and the /n defines the mask

25 Address Allocation The next issue in classless addressing is address allocation. How are the blocks allocated? The ultimate responsibility of address allocation is given to a global authority called the Internet Corporation for Assigned Names and Addresses (ICANN). However, ICANN does not normally allocate addresses to individual organizations. It assigns a large block of addresses to an ISP. Each ISP, in turn, divides its assigned block into smaller subblocks and grants the subblocks to its customers. In other words, an ISP receives one large block to be distributed to its Internet users. This is called address aggregation: many blocks of addresses are aggregated in one block and granted to one ISP

26 Network Address translation (NAT). NAT enables a user to have a large set of addresses internally and one address, or a small set of addresses, externally. The traffic inside can use the large set; the traffic outside, the small set. To separate the addresses used inside the home or business and the ones used for the Internet, the Internet authorities have reserved three sets of addresses as private Addresses 19.26

27 Figure Addresses in a NAT All the outgoing packets go through the NAT router, which replaces the source address in the packet with the global NAT address. All incoming packets also pass through the NAT router, which replaces the destination address in the packet (the NAT router global address) with the appropriate private address. Figure shows an example of address translation

30 Figure An ISP and NAT NAT and ISP An ISP that serves dial-up customers can use NAT technology to conserve addresses. For example, suppose an ISP is granted 1000 addresses, but has 100,000 customers. Each of the customers is assigned a private network address. The ISP translates each of the 100,000 source addresses in outgoing packets to one of the 1000 global addresses; it translates the global destination address in incoming packets to the corresponding private address. Figure shows this concept.

31 19-2 IPv6 ADDRESSES Despite all short-term solutions, address depletion is still a long-term problem for the Internet. This and other problems in the IP protocol itself have been the motivation for IPv6. Topics discussed in this section: Structure Address Space 19.31

32 Note An IPv6 address is 128 bits long

33 19.33 Figure IPv6 address in binary and hexadecimal colon notation

34 19.34 Figure Abbreviated IPv6 addresses

35 Example Expand the address 0:15::1:12:1213 to its original. Solution We first need to align the left side of the double colon to the left of the original pattern and the right side of the double colon to the right of the original pattern to find how many 0s we need to replace the double colon. This means that the original address is

### TCP/IP works on 3 types of services (cont.): TCP/IP protocols are divided into three categories:

Due to the number of hardware possibilities for a network, there must be a set of rules for how data should be transmitted across the connection media. A protocol defines how the network devices and computers
