IP address serving
In addition to being a router, the Netopia R310 is also an IP address server. There are three protocols it can
use to distribute IP addresses.
■ The first, called Dynamic Host Configuration Protocol (DHCP), is widely supported on PC networks, as
well as Apple Macintosh computers using Open Transport and computers using the UNIX operating system.
Addresses assigned via DHCP are “leased” or allocated for a short 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 server, 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 part 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 temporary IP
address for the duration of their connection.
Since no two hosts can use the same IP address at the same time, make sure that the addresses distributed
by the Netopia R310 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.
To go to the IP Address Serving screen, select IP Address Serving in the System Configuration screen and
press Return.
