Figure 5 – Single Client Connection to IPG100 
 shows an example of a single client connection to an IPG100. A DSM800 (or a
computer, or a MBB100) is connected directly to the IPG100. 
1.7.2 TCP/IP Networks 
The networking protocol that is used for the communication between the server an
th
ransfer Protocol), and many others of the most popular applications on the Internet.  
The TCP/IP connection can be made over an Ethernet connection, a Wi-Fi connection, cellu
phone data connection, and many other types of media.  In fact, a single packet of TCP/IP 
data may traverse multiple types of media on its journey. The TCP/IP protocol is supported by 
ting systems, as well as Internet-connected cellular phones. 
Each computer on a TCP/IP network is identified by an IP address unique to that network. An 
IP address consists of four numbers, each ranging between 0 and 255, separated by periods.  
This is referred to a dotted decimal notation.  Examples of IP addresses in this format are 
10.0.0.1, and 62.12.31.188. 
The IP address may either be hard coded into the computer (this means that the address
static which makes the computer easier to find) or assigned at each startup by a DHCP 
(Dynamic Host Control Protocol) server, typically found as part of a router. The router can be 
ed to 
e a
reserve a specific address for the computer and then assign that sam
each time at startup. If the router chooses a different address each time, then the computer 
may be difficult to find on the network. This is not a problem for a client such as N2KView
®
, but 
servers such as a PC running N2KServer
®
 or the IPG100 must be at a known address.
