Page 219: Appendix C Ip Addresses And Subnetting
P P E N D I X IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
Page 220: Subnet Masks
Appendix C IP Addresses and Subnetting The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID. Figure 126 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask.
Page 221 Appendix C IP Addresses and Subnetting Table 66 Subnet Mask - Identifying Network Number OCTET: OCTET: OCTET: OCTET (192) (168) Network Number 11000000 10101000 00000001 Host ID 00000010 By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.
Page 222 Appendix C IP Addresses and Subnetting As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows: Table 68 Maximum Host Numbers MAXIMUM NUMBER OF SUBNET MASK HOST ID SIZE HOSTS 8 bits 255.0.0.0...
Page 223 Appendix C IP Addresses and Subnetting Subnetting You can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons. In this example, the company network address is 192.168.1.0.
Page 224 Appendix C IP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two sub-networks, A and B. Figure 128 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of –...
Page 225 Appendix C IP Addresses and Subnetting Each subnet contains 6 host ID bits, giving 2 - 2 or 62 hosts for each subnet (a host ID of all zeroes is the subnet itself, all ones is the subnet’s broadcast address). Table 70 Subnet 1 LAST OCTET BIT IP/SUBNET MASK...

Private IP Addresses Every machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems.

Page 247: Appendix E Wireless Lans
P P E N D I X Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS).
Page 248 Appendix E Wireless LANs with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other. Figure 153 Basic Service Set An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network.
Page 249 Appendix E Wireless LANs An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate. Figure 154 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area.
Page 250 Appendix E Wireless LANs wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 155 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel.
Page 251: Fragmentation Threshold
Appendix E Wireless LANs Fragmentation Threshold A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames. A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.
Page 252 Appendix E Wireless LANs several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows: Table 77 IEEE 802.11g DATA RATE MODULATION (MBPS) DBPSK (Differential Binary Phase Shift Keyed) DQPSK (Differential Quadrature Phase Shift Keying) 5.5 / 11 CCK (Complementary Code Keying) 6/9/12/18/24/36/...
Page 253: Types Of Authentication
Appendix E Wireless LANs Types of RADIUS Messages The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication: • Access-Request Sent by an access point requesting authentication. • Access-Reject Sent by a RADIUS server rejecting access. •...
Page 254 Appendix E Wireless LANs However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication.
Page 255 Appendix E Wireless LANs If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled. Note: EAP-MD5 cannot be used with dynamic WEP key exchange For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption.
Page 256 Appendix E Wireless LANs TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
Page 257: Wpa(2)-Psk Application Example
Appendix E Wireless LANs 24.5.2 WPA(2)-PSK Application Example A WPA(2)-PSK application looks as follows. First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters (including spaces and symbols).
