Netopia r3100-u 参考指南

In addition to being a router, the Netopia R3100 is also an IP address ser ver. There are four protocols it can 
use to distribute IP addresses. 

■

The first, called Dynamic Host Configuration Protocol (DHCP), is widely suppor ted on PC networks, as 
well as Apple Macintosh computers using Open Transpor t and computers using the UNIX operating system. 
Addresses assigned via DHCP are “leased” or allocated for a shor t period of time; if a lease is not 
renewed, the address becomes available for use by another computer. DHCP also allows most of the IP 
parameters for a computer to be configured by the DHCP ser ver, simplifying setup of each machine.

■

The second, called BOOTP (also known as Bootstrap Protocol), is the predecessor to DHCP and allows 
older IP hosts to obtain most of the information that a DHCP client would obtain. However, in contrast, 
BOOTP address assignments are “permanent” since there is no lease renewal mechanism in BOOTP.

■

The third protocol, called Dynamic WAN, is par t of the PPP/MP suite of wide area protocols used for WAN 
connections. It allows remote terminal adapters and NAT-enabled routers to be assigned a temporar y IP 
address for the duration of their connection.

■

The four th protocol, called MacIP, is used only for computers on AppleTalk networks. MacIP provides a 
protocol translation (or gateway) function between IP and AppleTalk as well as an IP address assignment 
mechanism. Like DHCP, MacIP address assignments are normally temporar y, although you may also use 
static IP addresses with MacIP.

Since no two hosts can use the same IP address at the same time, make sure that the addresses distributed 
by the Netopia R3100, and those that are manually configured are not the same. Each method of distribution 
must have its own exclusive range of addresses to draw from.
