5 Addresses & Names Hardware (Layer 2) Lowest level Ethernet (MAC), Serial point-to-point,.. Network (Layer 3) IP IPX, SNA, others Application (layer 5?) Names (URL), alias,.. All are important and needed Ultimately, all deliveries move over the physical layer Note: Port address not under discussion (Transport) 5
6 Layer 2 Addressing Uses MAC address Assigned to end devices 6
7 Layer 3 Addressing Each Network Architecture has its own Layer 3 address format. OSI uses NSAP. TCP/IP uses IP 7

18 (Classical) (Layer 3) IP address is 32 bit An An IP address is broken in two parts Network address Host address Network host The division between network and host is determined by the size of network and determined by the class of the address 18
19 IP Addresses classful addressing class A B C 0 network host 10 network host 110 network host to to to D 1110 multicast address 32 bits to
20 IP Addresses IP Classful Addresses: Class A addresses begin with 0xxx, or 1 to 126 Class B addresses begin with 10xx, or 128 to 191 Class C addresses begin with 110x, or 192 to 223 Class D addresses begin with 1110, or 224 to 239 Multicast Class E addresses begin with 1111, or 240 to 254 Experimental 20
21 Classful Addressing Number of elements in each class Class Number of classes Number of local addresses A 0xxx ,777,216 B 10xx 16,384 65,534 C 110x 2,097,
22 Private IP Addresses Space Private IP Networks Class of Network Number of Networks to A to B to C 256 Note: The third column is the Number of Networks (and not IP Addresses) 22
23 Problems with Classful Addressing Inefficient use of address space, address space exhaustion e.g., class B net allocated enough addresses for 65K hosts, even if only 2K hosts in that network Network manageability (discussed below) No longer formally part of IP addressing architecture Note: A classful address identifies the Network and Host field No need for Network Mask! 23
24 Manageability: Flat Topology Problems All devices share the same bandwidth. All devices share the same broadcast domain. It is difficult to apply a security policy. 24
25 Manageability: Subnetworks The Smaller networks are easier to manage. Overall traffic is reduced. You can more easily apply network security policies. 1-25
26 IP addressing: CIDR CIDR: Classless InterDomain Routing Adopted by IETF in 1993 Network (subnet) portion of address of arbitrary length address format: a.b.c.d/x, where x is # bits in network (subnet) portion of address To support 2000 hosts, a block of 2048 addresses of the form a.b.c.d/21 assigned 11 bits needed to store 2048 (2 11 =2048) In practice the 11 bit rightmost addressing could be further divided (subnetting, more on this later) network part host part /21 26
27 Network Mask With CIDR, address no longer specifies the network portion Mask is used to extract network portion from an IP Address A string of 32 bits Bits corresponding to network (and subnet) part set to 1 Bits corresponding to host part set to 0 Ex (classful address): Addr = /8 = Mask = =
28 Mask examples (classful addresses) Ex-1: Addr = /8 = Mask = = N-Adr= Ex-2 Addr = /19 = Mask = = N-Adr=
29 Two-Level and Three-Level Addresses Inefficiency of two-level addresses A third level of addressing, consisting of subnets, was developed Subnet address: The original classful network portion plus a subnet field Also known as extended network field Subnet and host field created from the original classful host portion Subnet Mask helps identify the host/network part of an address 29
30 What a Subnet Mask Does Tells the router the number of bits to look at when routing Defines the number of bits that are significant Used as a measuring tool, not to hide anything 30
31 Possible Subnets and Hosts for a Class C Network 31
32 Possible Subnets and Hosts for a Class B Network 32
33 Possible Subnets and Hosts for a Class A Network 33
34 End System Subnet Mask Operation 34
35 Topology Example A network topology using one IP network with six subnets 35
36 How Routers Use Subnet Masks 36
37 Working with subnets and masks: Analysis Analysis of a given IP address/mask Binary/decimal mask Subnet number (network prefix) Next/previous subnet Range of addresses Broadcast address The first IP address The last IP address Important: are networks specified by 2 addresses overlapping? 37
38 Working with subnets and masks: Design Choosing a subnet mask to meet design requirements Finding the only possible mask Finding multiple possible masks Choosing the mask that maximizes the number of subnets or hosts 38
39 Subnet addresses Reserved addresses: The smallest address (all 0 s) signifies the subnet number /28: x.y.z /26: x.y.z The last address (all 1 s) signifies the broadcast address /28: x.y.z /26: x.y.z
40 Subnetting: A useful reference chart 40
41 Example: /28 (Class C) Borrowed bits: 4; Net bits: 28; Host bits: 4 Block size 16 Mask(last byte only): ; 240 Subnet number: ( ) Next/previous subnets: Next: = 144 ( ) Previous: = 112 ( ) Range of addresses: x.y.z.129 to x.y.z.143 Broadcast address: First IP address: Last IP address:
42 Example: /22 (Class B) Borrowed bits: 6; Net bits: 22; Host bits: 10 Block size: 4 (in the 3 rd byte) Mask: ; Subnet number: ( ) Next/previous subnets: Next: 16+4=20 ( ) Previous: 16-4=12 ( ) Range of addresses: to ) Broadcast address: First IP address: Last IP address:
43 Example: /12 (Class A) Borrowed bits: ; Net bits: ; Host bits: Block size: (in the byte) Mask: Subnet number: Next/previous subnets: Next: Previous: Range of addresses: Broadcast address: First IP address: Last IP address: 43
44 The Dread of Overlapping Subnets In designing networks, care should be taken to prevent overlapping subnets Step 1: calculate the subnet number and subnet broadcast address of each subnet. Determines range of addresses within each subnet Step 2: Compare the range of addresses in each subnet and look for any overlap 44
45 The Dread of Overlapping Subnets Is there any flaw in the following network? 45
46 Problem Network / / /24 46
47 The Dread of Overlapping Subnets /23 Mask: Subnet number: /23 Mask: Subnet number: /24 Mask: Subnet number: Overlap! 47
