(“dynamically”) by a device called a DHCP (Dynamic Host Configuration Protocol) server on your network. If you enabled DHCP when you set up the ZoomAir AP11 and the ZoomAir client cards, the wireless portion of your LAN has already been set up with dynamic IP addresses using the DHCP server built into the AP11 (see Chapter 1). -
Page 30: Implementing Dhcp In Wired Clients
• If you have a moderate-to-large wired LAN that is already served by a DHCP server other than the ZoomAir AP11, you can use WebManage to (1) change the ZoomAir AP11 address to one that is compatible with the wired LAN and (2) disable DHCP on the ZoomAir AP11. - Page 31 The goal is to get a unique static IP address for the ZoomAir AP11 unit that is part of the “family” of available addresses for your existing LAN. You will also need your LAN’s Netmask (255.255.255.0 unless your LAN has subnets).
- Page 32 Using WebManage to Change the ZoomAir AP11’s IP Address. You can change the IP address of the ZoomAir AP11 unit from any computer on your network. The computer must have Netscape Navigator 4.0 or later, or Internet Explorer 4.0 or later.

Page 65: Appendix Cip Networking Basics
Appendix C IP Networking Basics What is TCP/IP? The TCP/IP family of protocols is named after two of its most important members: Transmission Control Protocol and Internet Protocol. Each protocol in the family controls a specific task relating to the transfer of data over the Internet. Together these protocols manage a set of complex operations that the user—or even an application—thinks of simply as “sending mail”... -
Page 66: Ip Addressing
IP Addressing Put simply, TCP/IP works by addressing a packet with the unique address of its destination and then dispatching it over a network, where the destination node “listens” for packets with its address. Each node on a network must have its own unique address. Network 1 Device 1.1 sends directly to 1.2... -
Page 67: Classes Of Ip Addresses
There is a hierarchical organization inherent in this arrangement. IP addresses are divided into two segments. The network segment, which identifies the local network, is represented by the leftmost bits of the IP address. The host segment, which identifies a specific node on the network—a computer or a router—is represented by the rightmost bits of the address. -
Page 68: Ip Subnetting
Two other classes of addresses occupy the remainder of the address space from 224 - 247: Class D (used for IP multicasting) and Class E (reserved for experimental use). IP networks use a netmask (also known as a subnet mask) to indicate which portion of the address is used for the network address and which portion is used for the host address. -
Page 69: Example: Using Subnets On A Class C Ip Internet
assigned network number will share a subnet mask. To configure subnets properly, you must be able to convert between binary and decimal notation. To know whether subnets are in use, you must know what subnet mask is being used; you cannot determine this information from an IP address. - Page 70 machines each. (There are 30 host addresses available instead of 32 because the top and bottom addresses are reserved for broadcasting within the subnet.) Step 2 is to calculate the subnet mask. Since we are allocating the 3 leftmost bits of the final byte for subnet information, Acme’s subnet mask becomes 1111111.11111111.11111111.11100000 in binary notation.
-
Page 71: Broadcast Addresses
First, there is the broadcast address that spans the entire network. Then, each subnet has its own broadcast address. When configuring an IP network interface for the ZoomAir AP11, it is the latter subnet broadcast address that you should use. -
Page 72: Network Time Protocol
ZoomAir AP11 can then stamp each log and diagnostic message with a time and date. You can configure the ZoomAir AP11 with the IP address of an NTP server and indicate how often the NTP server should check the current time. If your organization has an NTP server, you should use the IP address of that server. -
