Dynamic IP Addressing
The HotWire DSLAM system allows the use of Dynamic Host Configuration
Protocol (DHCP) to facilitate the automatic assignment of end-user system IP
addresses. With the dynamic IP addressing feature, NSPs can administer IP
addresses to the end users dynamically (automatically) rather than statically
(manually). An IP address can be reused once the end user no longer requires
the address (i.e., the end-user system no longer requires access to the NSP) or
the lease time has expired. This feature allows NSPs to maintain a pool of IP
addresses that services many end users rather than one fixed IP address per
end-user system.
In addition, an authentication feature can also be configured to confirm an end-
user system’s access location.
For more information about dynamic routes, see Chapter 6,

Recording Your Configuration Settings
It is recommended that you keep a record of your configuration settings when
assigning IP addresses to the devices on your network.
Appendix A
,
Network
Configuration Worksheets, contains the worksheets to help you record those
settings. Store the worksheets for reference, as needed.
You may also save your configuration settings (download your code) on the TFTP
server. For more information, see Chapter 5,
